Send Number
Broadcasts a number data packet to other micro:bits connected via radio.
Parameters
- packet - a number to be transmitted.
Examples
Broadcasts the value of acceleration x to other micro:bits.
input.onButtonPressed(Button.A, () => {
radio.sendNumber(input.acceleration(Dimension.X))
})
Light level sender
This example broadcasts the level of the light around it:
radio.setGroup(99)
basic.forever(() => {
let level = input.lightLevel()
radio.sendNumber(level)
})
This example shows the light level from the sender (above):
radio.setGroup(99)
basic.forever(() => {
let level = radio.receiveNumber()
basic.showNumber(level)
})
Mailbot
This example takes the signal from the light level sender (above) and shows a text string if the light level becomes much brighter. You can put the light level sender in your mailbox and it will tell you when someone opens the box. You can try this with a normal box too, like a present.
radio.setGroup(99)
let max = 0
basic.forever(() => {
let level = radio.receiveNumber()
if (level > max) {
max = level
}
if (max > 10) {
basic.showString("ALERT")
}
})
