EDU:BIT Extension for Microsoft MakeCode

This code provides the driver for EDU:BIT Training & Project Kit for micro:bit. EDU:BIT works with micro:bit V1 & V2.

EDU:BIT is specially designed to encourage kids to explore STEAM and learn coding. It comes with a booklet covering 10+1 hands-on coding lessons, which have been creatively structured to introduce programming basics in a fun and engaging manner. Each chapter features a classic childhood game such as Rock Paper Scissors, Snakes and Ladders, Twister, and Simon Says. Follow the step-by-step guide to build the games and then have fun playing with your friends!

Examples

Music Bit

Music Bit works with the default ||Music|| blocks that comes with MakeCode. Play melody once at program start-up.

music.beginMelody(music.builtInMelody(Melodies.PowerUp), MelodyOptions.Once)

Sound Bit

Show sound level.

basic.forever(function () {
    basic.showNumber(edubitSoundBit.readSoundSensor())
})

Show sad face when it’s too noisy.

basic.forever(function () {
    if (edubitSoundBit.compareSoundSensor(SoundSensorCompareType.MoreThan, 512)) {
        basic.showIcon(IconNames.Sad)
    } else {
        basic.clearScreen()
    }
})

Count claps.

let count = 0
edubitSoundBit.onEvent(SoundSensorCompareType.MoreThan, 512, function () {
    count += 1
})

Potentio Bit

Plot graph to show the potentiometer value.

basic.forever(function () {
    led.plotBarGraph(
    edubitPotentioBit.readPotValue(),
    1023
    )
})

Show heart shape when the potentiometer is turned to the max.

basic.forever(function () {
    if (edubitPotentioBit.comparePot(PotCompareType.MoreThan, 1000)) {
        basic.showIcon(IconNames.Heart)
    } else {
        basic.clearScreen()
    }
})

Another way of showing heart shape when the potentiometer is turned to the max.

edubitPotentioBit.onEvent(PotCompareType.MoreThan, 1000, function () {
    basic.showIcon(IconNames.Heart)
})
edubitPotentioBit.onEvent(PotCompareType.LessThan, 1000, function () {
    basic.clearScreen()
})

IR Bit

Show the IR sensor state.

basic.forever(function () {
    basic.showNumber(edubitIrBit.readIrSensor())
})

Show a target symbol when an object is detected.

basic.forever(function () {
    if (true) {
        basic.showIcon(IconNames.Target)
    } else {
        basic.clearScreen()
    }
})

Play a melody everytime an object is detected.

edubitIrBit.onIrSensorEvent(IrEventType.Rise, function () {
    music.beginMelody(music.builtInMelody(Melodies.Ringtone), MelodyOptions.Once)
})

RGB Bit

Clear all RGB pixels.

edubitRgbBit.clear()

Show rainbow color on all RGB pixels and change the brightness to maximum.

edubitRgbBit.showRainbow()
edubitRgbBit.setBrightness(255)

Show color green on all RGB pixels and change the color one by one to red.

edubitRgbBit.showColor(0x00ff00)
basic.pause(1000)
edubitRgbBit.setPixelColor(0, 0xff0000)
basic.pause(500)
edubitRgbBit.setPixelColor(1, 0xff0000)
basic.pause(500)
edubitRgbBit.setPixelColor(2, 0xff0000)
basic.pause(500)
edubitRgbBit.setPixelColor(3, 0xff0000)

Show rainbow color and shift it out one by one.

edubitRgbBit.showRainbow()
basic.pause(500)
edubitRgbBit.shiftPixels(1)
basic.pause(500)
edubitRgbBit.shiftPixels(1)
basic.pause(500)
edubitRgbBit.shiftPixels(1)
basic.pause(500)
edubitRgbBit.shiftPixels(1)

Show rainbow color and rotate it.

edubitRgbBit.showRainbow()
basic.forever(function () {
    edubitRgbBit.rotatePixels(1)
    basic.pause(500)
})

Traffic Light Bit

Blink the yellow LED.

basic.forever(function () {
    edubitTrafficLightBit.toggleLed(LedColor.Yellow)
    basic.pause(500)
})

Show running light on the LEDs.

basic.forever(function () {
    edubitTrafficLightBit.setLed(LedColor.Red, 1)
    edubitTrafficLightBit.setLed(LedColor.Yellow, 0)
    edubitTrafficLightBit.setLed(LedColor.Green, 0)
    basic.pause(200)
    edubitTrafficLightBit.setLed(LedColor.Red, 0)
    edubitTrafficLightBit.setLed(LedColor.Yellow, 1)
    edubitTrafficLightBit.setLed(LedColor.Green, 0)
    basic.pause(200)
    edubitTrafficLightBit.setLed(LedColor.Red, 0)
    edubitTrafficLightBit.setLed(LedColor.Yellow, 0)
    edubitTrafficLightBit.setLed(LedColor.Green, 1)
    basic.pause(200)
})

Button Bit

Button Bit is connected in parallel with micro:bit button A and B. It works with the default ||Input|| blocks that comes with MakeCode. Play melody when button A is pressed.

input.onButtonPressed(Button.A, function () {
    music.beginMelody(music.builtInMelody(Melodies.Birthday), MelodyOptions.Once)
})

DC Motors

Run Motor 1 forward at 50% speed when button A is pressed, brake the motor when button B is pressed.

input.onButtonPressed(Button.A, function () {
    edubitMotors.runMotor(MotorChannel.M1, MotorDirection.Forward, 127)
})
input.onButtonPressed(Button.B, function () {
    edubitMotors.brakeMotor(MotorChannel.M1)
})

Servos

Button A pressed - Rotate Servo 1 to 0 degree. Button B pressed - Rotate Servo 1 to 180 degree. Button A+B pressed - Disable Servo 1. No pulse is sent to Servo 1 and it can be rotated by hand.

input.onButtonPressed(Button.A, function () {
    edubitMotors.setServoPosition(ServoChannel.S1, 0)
})
input.onButtonPressed(Button.B, function () {
    edubitMotors.setServoPosition(ServoChannel.S1, 180)
})
input.onButtonPressed(Button.AB, function () {
    edubitMotors.disableServo(ServoChannel.S1)
})
