Makey Makey Code-a-Key MakeCode Package

This extension integrates the Makey Makey with the micro:bit through the Code-a-Key backpack. It allows you to program the micro:bit for keyboard and mouse interactions, responding to key presses and mouse clicks from the Makey Makey.

Basic Blocks

Initialize Makey Makey

The initialize Makey Makey block is essential and should be placed at the start of your On Start event block.

// initialize Makey Makey block
MakeyMakey.sx1509Init()

Press and Release Key

Simulates a key press and release sequence with an adjustable delay.

// press and release Key block
MakeyMakey.typeKey(KeyPress.W)

Press Key

Holds a key down until released.

// press key block
MakeyMakey.pressKey(KeyPress.W)

Release Key

Releases a key that was held down.

// release key block
MakeyMakey.release(KeyRelease.W)

When Makey Makey Key Pressed

Triggers an event when the Makey Makey sends any key press to the computer.

// when key pressed block
MakeyMakey.whenKeyPressed(() => {
  // Code to execute when a key is pressed
})

Click Mouse Button

Mimics a mouse click, consisting of a mouse down and up event.

// click mouse button block
MakeyMakey.clickMouse(MouseButtons.Left)

Move Mouse for Milliseconds

Moves the mouse cursor in a specified direction for a set duration.

// move mouse for ms block
MakeyMakey.moveMouseForMilliseconds(MouseDirections.Up, 1000)

When Makey Makey Mouse clicked

Triggers an event when the Makey Makey sends a left or right mouse click to the computer.

// when makey makey mouse clicked block
MakeyMakey.whenMouseClicked(() => {
  // Code to execute when a mouse button is clicked
})

Advanced Blocks

These blocks offer more control over key and mouse button presses, allowing for complex behaviors.

Press Mouse Button

Holds down a mouse button until released.

// press mouse button block
MakeyMakey.pressMouseButton(MouseButtons.Left)

Release Mouse Button

Releases a mouse button that was held down.

// release mouse button block
MakeyMakey.releaseMouseButton(MouseButtons.Left)

Begin Moving Mouse

// begin moving mouse block
MakeyMakey.moveMouse(MouseDirections.Up)

Stop Mouse

Stops the mouse from moving in a given direction.

// stop mouse block

Set Debounce

Adjusts the debounce timing for press-and-release and click actions.

// set debounce block
MakeyMakey.setDebounce(100)

Set polling rate

Sets the polling rate for the Makey Makey input event blocks. The default rate is 20ms. This is how often the micro:bit will check for changes in the state of the Makey Makey input pins

// set polling rate block
MakeyMakey.setPollingRate(50)

    // Code to execute when all keys and/or mouse buttons are released
})

When Makey Makey Keys or Mouse Buttons Pressed

Executes code when the Makey Makey transitions from having zero keys and/or mouse buttons pressed to any keys and/or mouse buttons pressed.

// when Makey Makey pressed block
MakeyMakey.onReleaseEvent(MakeyMakeyReleaseEventTypes.AllReleased, () => {
    // Code to execute when any keys and/or mouse buttons are pressed
})

Set Debounce Time

Configures the debounce time for key and mouse events.

// Set Debounce Time block
MakeyMakey.setDebounce(100) // Set the debounce time in milliseconds

Checks if any Makey Makey key is currently pressed.

// Any Key Pressed block
let isAnyKeyPressed = MakeyMakey.anyKeyPressed()
