### Example: Broadcasting acceleration
2016-06-17 00:15:14 +02:00
This program sends your micro:bit's **acceleration** (amount it is
speeding up or slowing down) 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.
2016-06-15 14:09:40 +02:00
```blocks
2016-06-17 00:33:35 +02:00
radio.setGroup(99)
2016-06-15 14:09:40 +02:00
input.onButtonPressed(Button.A, () => {
radio.sendValue("acc", input.acceleration(Dimension.X))
2016-06-15 14:09:40 +02:00
})
```
2016-06-17 00:15:14 +02:00
This program receives the string and number sent by the last program.
Then it shows them on the LED screen.
```blocks
2016-06-17 00:33:35 +02:00
radio.setGroup(99)
radio.onDataPacketReceived(({ receivedString, receivedNumber }) => {
basic.showString(receivedString);
basic.showNumber(receivedNumber);
2016-06-17 00:15:14 +02:00
});
```
