# Send Number
|
|
|
|
Broadcast a (name,number) pair to other micro:bits connected via ``radio``.
|
|
|
|
### Parameters
|
|
|
|
* name - a string to send
|
|
* num - a number to send.
|
|
|
|
### Simulator
|
|
|
|
This function only works on the micro:bit, not in browsers.
|
|
|
|
### Example: 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.
|
|
|
|
```blocks
|
|
input.onButtonPressed(Button.A, () => {
|
|
radio.sendValue("acc",input.acceleration(Dimension.X))
|
|
})
|
|
```
|
