Examples

Broadcasting acceleration

This example broadcasts the value of your @boardname@'s acceleration in the x direction (left and right) to other @boardname@s. This kind of program might be useful in a model car or model rocket.

input.onButtonEvent(Button.A, ButtonEvent.Click, () => {
    radio.sendNumber(input.acceleration(Dimension.X))
})

Light level sender

This example broadcasts the level of the light around it. You can do some interesting things with it if you use it along with the on received number example.

radio.setGroup(99)
basic.forever(() => {
    let level = input.lightLevel()
    radio.sendNumber(level)
})
