Watch this video to see how the radio hardware works on the micro:bit:
send Number
Broadcast a number to other micro:bits connected via radio
.
radio.sendNumber(0);
Parameters
- value: a number to send.
Examples
Broadcasting acceleration
This example broadcasts the value of your micro:bit’s acceleration
in the x
direction (left and right) to other micro:bits. This kind
of program might be useful in a model car or model rocket.
input.onButtonPressed(Button.A, () => {
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)
})
