Acceleration

Get the acceleration value (milli g-force), in one of three specified dimensions.

input.acceleration(Dimension.X);

Parameters

dimension : String - one of three values specifying the axis of acceleration: x (left/right); y (forward/backwards); z (up/down)

Returns

Number - acceleration, in milli-gravities. When the micro:bit is laying flat with the screen up, x=0, y=0 and z=-1023.

Example: bar chart

Use the plot bar chart to visual the acceleration on the LED screen.

basic.forever(() => {
    led.plotBarGraph(input.acceleration("x"), 1023)
})

Example: micro:bit leveller

The following example uses the acceleration and the plot function to help you move the micro:bit until it's level (the centre LED is on when the device is level). When running this code in a web browser, move your mouse to simulate the accelerometer.

basic.forever(() => {
    let ax = input.acceleration(Dimension.X)
    let x = pins.map(-1023, 1023, 0, 4, ax)
    let ay = input.acceleration("y")
    let y = pins.map(-1023, 1023, 0, 4, ay)
    basic.clearScreen()
    led.plot(x, y)
})
