      "body": "Use this spirit level to quickly and easily display the tilt of any object attached!\n\nCreated by Kaitlyn from Raffles Institution.\n\nGoals\n\nLearn to read tilt with micro:bit's built-in accelerometer.\n\nLearn to work with micro:bit's 5x5 LED Display!\n\nMaterials\n\n1 x BBC micro:bit\n\n1 x Micro USB cable\n\n2 x AA Batteries\n\n1 x Double AA Battery Pack\n\nPre Coding: Connect your Micro:Bit\n\nConnect the BBC micro:bit to your computer using a micro USB cable.\nAccess the javascript editor for the micro:bit at makecode.microbit.org.\n\n\nStep 0: Code Flow\n\nBefore we begin writing the code, we need to decide what we want to achieve with the program and in what order should each component run.\n\nFor the electric spirit level, the steps that we will take in the code for each loop are:\n\nRead tilt readings from accelerometer.\nConvert tilt readings to tilt levels to be displayed on LED matrix.\nCheck for change in tilt level readings from previous loop.\nCreate array of LED coordinates for different tilt cases and directions.\nPlot LED coordinates onto micro:bit LED matrix.\nA few additional functions we need to include are:\n\nCalibration for initial tilt position.\nReturning to default tilt calibration.\n\n\nStep 1: Defining Variables\n\nWe start by defining variables needed as shown. A breakdown of a few variables are:\n\ntiltList: Array that stores extent of tilt from values 0-4 in the order [Left, Right, Forward, Backward]\ntiltBoundary: Boundary of the first tilt level between 0 (no tilt) and 1 (slight tilt)\nprevState: Array that stores the tilt values of the micro:bit from a previous loop in the same format as tiltList, used to check for a change in tilt between iterations\nledPlotList: Plot led coordinate arrays in the form (x, y). To define an array , we use the type number[][] to indicate a nested array of variables of type: number.\n\n\nStep 2: Convert tilt values to levels\n\nAs the 5x5 LED matrix can only display so much information, the actual tilt values will not be useful for display.\n\nInstead, a function tiltExtent() takes the parameter num, which refers to the tilt value from the accelerometer, and converts these tilt values (num) to tilt levels from 0 to 4.\n\n0 indicates no tilt in the given direction and 4 indicates very large tilt, while -1 is returned when there is an error.\n\nHere, tiltBoundary and tiltSensitivity are used as the boundary values between tilt levels.\n\n\n\nStep 3: Compile tilt levels\n\nThe two functions checkRoll() and checkPitch() write the tilt levels obtained from tiltExtent() into tiltList for the roll (left-right) and the pitch (forward-backward) axes respectively.\n\nBefore using the tilt values, we calibrate them using a zeroed value for both pitch (zeroPitch) and roll (zeroRoll) obtained from a calibration function written later.\n\nAs the accelerometer readings are negative for both left and forward tilt, we need to use the Math.abs() function to obtain the modulus of the negative value to be given to the tiltExtent() function as a parameter for these two directions.\n\n\n\nStep 4: Write LEDPlotList Functions\n\nHaving obtained the tilt levels in tiltList we can now write the led plotting functions for the different cases that can arise, namely\n\nplotSingle(): Tilt only in a single direction, taking extent of tilt in given direction as parameter.\nplotDiagonal(): Tilt in two directions of the same magnitude, taking extent of tilt in either direction as parameter.\nplotUnequal(): Tilt in two directions of different magnitudes, taking extent of tilt in each direction as parameter. Uses plotDiagonal() first and adds on to ledPlotList array afterwards.\nThese plotting functions write an array of led coordinates to ledPlotList to be plotted later on.\n\n\n\n\n\n\n\nStep 5: Plot LED Matrix for Each Case\n\nUsing the plotting functions from the three cases in step 4, we can now plot the actual LED matrix for the different possible combinations of tilt levels. As the three functions in step 4 do not discriminate with direction, we need to adjust the coordinate values passed to the LED matrix to plot the LEDs in the right directions.\n\n\n\n\n\nPlotResult() contains multiple if conditions that check the kind of tilt and plot the LED matrix accordingly using led.plot(x, y). The possible combinations of tilt are:\n\nSingle direction: Left Only or Right Only.\n\n\nSingle direction: Forward Only or Backward Only.\n\n\nTwo directions: Forward-left or Backward-left.\n\n\nTwo directions: Forward-right or Backward-right.\n\n\nNote: For tilt in two directions, each combination can have the same or different magnitude (checked by comparing maxX and maxY), and hence plotted using plotDiagonal() or plotUnequal() respectively.\n\nStep 6: Write Calibration Functions\n\nHaving completed the bulk of the code, we now add in the calibTilt() and the resetTilt() functions.\n\ncalibTilt() allows users to tare the tilt to zero at the micro:bit's current position\n\nresetTilt() resets the calibration of the board to its original state.\n\n\n\nStep 7: Write State Function\n\nWe add a simple function checkState() to check whether the tilt levels have changed from a previous iteration.\n\nIf there is no change in tilt levels from a previous iteration i.e. stateChange == 0, we can directly move on to the next iteration and skip the plotting of the LED matrix, reducing computation needed.\n\n\n\nStep 8: Putting It All Together Part 1!\n\nNow we can finally place all the necessary functions into the micro:bit's infinite loop to run it repeatedly.\n\nFirstly, we set button A and B on the micro:bit to the calibTilt() and resetTilt() functions respectively using input.onButtonPressed(), and plot a tick on the LED matrix when calibration is completed.\n\n\n\nStep 9: Putting it All Together Part 2!\n\nNext run the necessary functions according to our code flow in Step 0 and check for a state change (meaning that there has a change in the tilt of micro:bit since the last iteration).\n\nIf there is a change in tilt levels i.e. stateChange == 1, the code will update prevState to the new tilt levels and set stateChange back to 0 for the next iteration, and plot the updated tilt levels on the LED matrix using PlotResult().\n\n\n\nStep 10: Assembly\n\nFlash the completed code to your micro:bit .\n\nAttach your micro:bit and the battery pack securely to any object and it is ready for use!\n\n\n\nAwesome!\n\nHave fun with your electric spirit level! And while you're at it, why not try to extend the capabilities of the tilt sensor or even turn it into a game?\n\nThis article is from TINKERCADEMY.\n\nhttps://www.elecfreaks.com/11632.html",

Here we have made a colorful crystal lamp with micro:bit board. Hope this will be a good choice for you. Just have a try!\n\n\n\nTools & Materials:\n\n1 x 8 RGB Rainbow LED Strip\n\n1 x BBC Micro:bit Board for Coding & Programming\n\n4 x 3*5 Copper Stud\n\n8 x 3*5 Screw\n\n1 x acrylic board\n\n\n\nWorking Principle:\n\nWe use laser engraving machine to carve patterns on the transparent acrylic board, and then install RGB LED light underneath. The light beam will emit from the carved area. We can also use highlighters to draw some wanted patterns on the acrylic board so as to realize the similar effect.\n\n\n\nHow to Make:\n\n\n\nStep 1:\n\nFirstly, we need to design an acrylic base. You can design it to any shape you like by yourself. We use laser engraving machine to cut two circles in same size from a transparent acrylic board. There are four small holes, which form a square within the circles. On one of the circles, we have made a hollow rectangle slot.\n\n\n\n\n\n\n\nStep 2: \n\nFix RGB LED strip to the hollow slot of the circle with screws. And then use copper studs to assemble the whole base together. You can install it according to the picture below.\n\n\n\n\n\n\n\nStep 3:\n\nNext, let's start to carve patterns for our lamp body. Under each pattern you carved, you shall spare a bottom base, which can be plugged into the acrylic base. You can choose some of your favorite cartoon figures or pictures, then draw it with CAD. In this case, what we have designed is a Christmas tree. Here's our sketches!\n\n\n\n\n\n\n\n\n\n\n\nStep 4:\n\nPlug the bottom base of the tree into the slot on the acrylic base.\n\n\n\nStep 5:\n\nConnect RGB LED strip to micro:bit. You can connect them according to the picture below.\n\n\n\n\n\n\n\nStep 6:\n\nHide your micro:bit board and cables well under the lamp body. Use a USB cable to connect your micro:bit board to computer. Till now, we have finished all of hardware installation. Next, we are going to program for our lamp and try to make it realize colorful light gradient.\n\n\n\n\n\n\n\nProgramming\n\nOpen Microsoft Makecode, write your code into the edit area. I would like to suggest you try to program by yourself first.\n\nOf course, you can see the whole program in the link below. Just click Edit on the upper right corner, then click Download underneath to download your code directly into micro:bit.\n\n\n\n\n\n\nResult:\n\nAmazing! The crystal lamp is glowing colorful lights!

      "body": "Introduction \n\nRing:bit is a simple module based on micro:bit. It can lead out 3 IO connectors, power connectors, ground connectors on the micro:bit board. On this module, we have transformed P0/P1/P2 into general connectors for GVS electric bricks. Among them, we have extended P2 to a GVS connector with multiple usages. There is a slide switch on the board. Slide the switch to \"S\", then you can connect SR and SL2 (digital signal modules) at the same time. Slide to \"P2\", you can connect digital module or simulating module but only one of them. This module adopts 3 No. 7 batteries for power supply. It is very simple, easy and practical to use. With this module, you can drive all kinds of GVS modules like servos, line-hunting modules and LED modules.\n\n\n\n1\n\n\nShipping List:\n\n1 x Ring:bit\n\nFeatures:\n\nDevelop Environment: Code Kingdoms Java script, Microsoft Blocks，Microsoft Touch Develop，Python\n\nSupport GVS connectors\n\nWith a switch, one IO connector can be repeatedly used for double channels.\n\nSmall size with multiple development for DIY.\n\nInput Voltage：DC 3.9V-4.5V\n\nDimension：65.00mm X 51.70mm\n\nWeight：27 g\n\nApplication:\n\nSupport Bluetooth 4.0 device (based on micro:bit)\n\nSupport 3 PIN GVS connector.

Shift to \"S\" means SR in P2 connected to SL. At this time, you can connect two GVS modules to connector G-V-SR and G-V-SL separately. Shift to \"P2\" means use the connector of P2 only.\n\n\n\nG-V-S P2 connector:\n\nOnly when function selection switch has shifted to P2，these two connectors can be used. It is compatible with partial products of Octopus Bricks series.\n\n\n\nG-V-S SR/SL Connector:\n\nOnly when function selection switch has shifted to S, we can use the connector. It is compatible with partial products of Octopus Bricks series.\n\n\n\nCode Example:\n\nElectric circuit for mini elephant car line-hunting:\n\n\n\n7\n\n\n\nFix micro:bit board:\n\n\n\n8\n\nG-V-S P0 Connector:\n\nP0 connector can be used as digital IO connector, analog IO connector or PWM output signal connector.\n\n\n\nG-V-S P1 Connector:\n\nP1 connector can be used as digital IO connector, analog IO connector or PWM output signal connector.\n\n\n\nDimension \n\n\n\nSoftware\n\nCode Example:\n\n\n\n12\n\n\n\nFix micro:bit board:\n\n\n\n\n\nThe three servos rotate clockwise first, anti-clockwise after 1 second, then clockwise again in the next 1 second.

      "body": "The so-called line follow car means a car follows a black line on the white(or light color)ground. Because the black line and white ground have different reflections to the light, the car can drive according the the strength of the light reflection received. Today, we are going to make a line follow car with micro:bit.\n\nenter image description here\n\nMaterials Needed:\n\n1 x BBC micro:bit\n1 x ELECFREAKS Motor:bit\n1 x Smart Car Chassis\n2 x Octopus Hunt Sensor\n2 x 3x12+6 Copper Rod\n3 x 3x10 Copper Rod\n2 x 18650 Battery\nBlack Adhesive Tapes\nSeveral Cables\nIn this project, we will mainly use micro:bit and motor:bit.\n\nMore details about micro:bit, you can read:Start Your Micro:bit Programming Trip\nMore details about motor:bit, you can read:Elecfreaks Motor:bit User Guide\n\nHardware Assembling\n\nStep 1\n\nWeld motor cables. If there are no lead cables on your motors, you have to weld cables for them.\n\nAlt text\n\nStep 2\n\nWithin the package of car chassis, there is a drawing for instruction. You can refer to its instructions and assemble the chassis.\nOnce finished, you will see the chassis below:\n\nAlt text\n\nStep 3\n\nFix motor:bit to the chassis of the car.\n\nAlt text\n\nStep 4\n\nPlug the two groups of motor cables into connector M1 and M2.\n\nAlt text\n\nStep 5\n\nInstall line follow modules and pay attention to their space. In this project, the space of two line follow modules is about or a little bit smaller than the width of the black adhesive tape.\n\nPlug the two line follow modules into P4 and P5 separately.\n\nAlt text\n\nStep 6\n\nConnect with 6~12v DC power supply. Here, we have connected 2 segments of 18650 batteries in parallel, and then plugged a micro:bit.\n\nAlt text\n\nYou can see the whole electric circuit in the below:\n\nAlt text\n\nStep 7\n\nDraw a trace on the ground with a black adhesive tape.\nYou have to pay attention to the width of the tape. It is a little bit bigger than the width of two line follow modules.\n\nStep 8\n\nPlease download the program below into micro:bit, watch out the rotating directions of the two motors. According to this program, the motors should both move forward. If one motor in the opposite direction, you have to change the cable connection of the motor in error and reconnect motor:bit.\n\nAlt text\n\nStep 9\n\nAdjust line follow module to enable recognition of black lines and white base board. If the recognition is not available, you can adjust the sensitivity of the potentiometer on the module.\n\nProgramming\n\nStep 1\n\nSince hardware connection is completed, we can start to edit our program now. In this case, lots of pins and micro:bit built-in LED dot matrix can be used repeatedly, so firstly we should turn off the LED screen.\n\nAlt text\n\nStep 2\n\nWrite program for forwarding, stopping, turning left and right. Control the rotate speed of the motor through analog wite. Bigger value it has, the motor rotates faster.\n\nAlt text\n\nStep 3\n\nAccording to the logic below, write your main program of line follow project.\n\nAlt text\n\nAlt text\n\nDownload Program：\n\nYou can click Download directly to save the code into micro:bit.\n\n\nView our little car on YouTube:\n\n \n\n \n\n\nRelative Readings\n\nMake A Cool Micro:bit Hovercraft Together",

      "body": "Last Saturday, I had paid a visit to 2017 Shenzhen Maker Faire Exhibition with one of my colleagues. It was just November 11, Chinese annual double 11 online shopping festival. I thought few people would go there because most of them would like to stay at home and stare at their mobile phones or computers to get the best products online. To my surprise, there were still a lot of people to go there.\n\n\n\nIt was my first time to visit a fair in Shenzhen. Because we were not sensitive to directions, we followed a group of people and maker faire banners till the entrance after we came out of the subway station. We had to stand in queue before we entered into the gate. This fair was held in a campus. The scenery was beautiful and the weather was good too. I saw a lot of maker faire banners and posters. I felt very happy to visit such a beautiful place. I had carried my camera and ready to get some good picture shots.\n\n\n\nMy first station was our Elecfreaks booth. Here's our products showed in the fair. If you want to know the usage of these products, you can focus on our blogs updated later. We will explain it in detail for you.\n\n\n\n\n\n\n\n\n\n\n\nOur colleagues were busy introducing our creations.\n\n\n\nThe fair atmosphere was quite good. People around us were attracted by the introduction of our colleagues. My colleagues were quite busy. So I entered the booth and tried to help them for a while. I was happy to play with children. They are very lovely and so clever!\n\nIn the following, we had seen more interesting products. We came to a big LED screen. I saw a lot of children paint on it with wet brushes. Someone told me that every stroke painted with wet brushes, the screen would display it with LED light and finally form a pattern. That's really amazing! I couldn't help to have a try. A heart appeared on the screen. I was quite satisfied with my artwork.\n\n\n\nWe moved on, then we saw a lot of people playing sticker balls. These colorful small balls are quite adhesive. You can use it to form any shapes you want. Look! There is a tree made of these small adhesive balls. It looks just like a christmas tree with many colorful light bulbs.\n\n\n\n\n\nWe went on to walk around. We found a lot of interesting creations. Like Micro:bit board and some robots.\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nThese creations are really very wonderful! I couldn't help to give them some shots.\n\n\n\nLED egg light. It is made of real egg shell! It is very exquisite.\n\n\n\nBanboo Charkha. It is actually a banboo spin device. It looks quite classical and environment protect. This device make me think of the people who live a slow and leisure life in ancient age.\n\n\n\nRobot hand. It looks like a flexible real hand. These fingers are made by 3D printer.\n\n\n\nA robot made with Micro:bit board. It has 12 servos in each junction and controlled by a main board connected to Micro:bit board. This robot is very cute.\n\n\n\nMagic mirror. It is made by raspberry pi. This mirror can tell you the current time, temperature and the weather.\n\n\n\n\n\nSome DIY music instrument. The effects are quite good!\n\nThe above are some of the funny creations that I personally think it quite special. If you had visited the fair, I think you might have more interesting findings than me.\n\nThe fair area is not very big actually. However, we almost walked from the east of the campus to the west of the campus. We were both very tired. After we finished our visit and prepared to go home, I had asked a foreigner to take a picture with me. I want to remember this wonderful fair. I never thought that I was so close to the whole world.",

      "body": "Introduction\n\nRGB LED is a kind of LED. It can emit light with three different colors: red, green, blue. In this experiment, we are trying to make RGB LED gradually shift its light among the three different colors.\n\nComponent List\n\nHardware:\n\n1 x Micro:bit Board\n\n1 x Micro-B USB Cable\n\n1 x Microbit Breadboard Adapter\n\n1 x Transparent Breadboard - 83 * 55 mm\n\n1 x RGB LED\n\n3 x 100 Ohm Resistors\n\n1 x Breadborad jumper wire 65pcs pack\n\nTips: If you want to buy all components above, you may need Elecfreaks Micro:bit Starter Kit.\n\n\n\nSoftware:\n\nMicrosoft Makecode Online Editor\n\nMajor Component Introduction\n\nRGB LED\n\nRGB LED is a kind of LED, which has integrated red LED, green LED, and blue LED into a component. We all knows that the three primary colors of light are red, green, and blue. With different groups of the three color lights, we can create all colors of the world. Similarly, if we use RGB LED to group lights with different brightness, then it can form various colors.\n\n\n\nRGB LED can be divided into 2 types: common anode and common cathode. In common-cathode RGB LED, its common port usually connects GND, while in common-anode RGB LED, its common port connects VCC. In this experiment, we choose common-cathode RGB LED .\n\nHardware Connection\n\nPlease complete hardware connection according to the picture below.\n\n\n\nAfter connection, you can see:\n\n\n\n\nProgramming\n\nOpen Microsoft Makecode, write code in edit area. I would like to suggest you program by yourself first.\n\nOf course, if you want to see the whole program directly, you can click the link below. Just click \"Edit\"on the right top corner of the interface you opened, then click \"Download\" on the right bottom to download code into micro:bit directly.\n\n\nCode Explanation\n\nChange Value\n\nSet the value for local and global variables. change r by 1 equals \"r=r+1\".\n\nrepeat\n\nRun part of the program the number of times you say.\n\nfunction\n\nA function is some amount of code you can reuse in your program. You create a function using a function definition which names the function and has its code. A function call is when you use a function by its name somewhere in your program.\n\ncall function\n\nUse a function by its name somewhere in a program.\n\n\n\nIn this experiment, we have set three variables: r、g、b, which is used to record brightness value of red light, green light, and blue light separately. At the initial status, only red light will be illuminated.\n\n\n\nThen we have to create 3 functions to realize gradual change among the three colors.\n\nFor example, \"RtoG\" function is for realizing transformation of red light and green light. If we implement the circulation of the function for once, then P0 analog input \"-1\"( red light brightness decreased a little bit)\n\n, and P1 analog input \"+1\" ( green light brightness increased a little bit). After implement circulation for 1023 times, P0 analog input become \"0\" (red light turned off), and P1 analog input becomes \"1023\"(green light illuminated). Finally, it has realized gradual change smoothly.\n\n\n\nCirculate the three functions to realize color gradual change smoothly.\n\nExperiment Result\n\nRGB LED light will shift among the three colors: red, green, and blue smoothly in balance.\n\n1\n\nQuestion:\n\nIf we want to use RGB LED to emit cyan light, magenta light, yellow light, then how to design circuit and program? We look forward to your comments or further discussions with us.\n\nRelative Readings:\n\nStart Your Micro:bit Programming Trip\n\nMicro:bit Experiment 01: LED Scroller —— Elecfreaks Mirco: bit Starter Kit Course\n\nMicro:bit Experiment 02: Button —— Elecfreaks Mirco: bit Starter Kit Course\n\nMicro:bit Experiment 03: Trimpot —— Elecfreaks Mirco: bit Starter Kit Course\n\nMicro:bit Experiment 04: Photocell — Elecfreaks Mirco: bit Starter Kit Course",
