# send Number
|
|
|
|
Broadcast a [number](/types/number) to other @boardname@s connected via ``radio``.
|
|
|
|
```sig
|
|
radio.sendNumber(0);
|
|
```
|
|
|
|
## Parameters
|
|
|
|
* **value**: a [number](/types/number) to send.
|
|
|
|
|
|
## 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.
|
|
|
|
```blocks
|
|
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](/reference/radio/on-received-number) example.
|
|
|
|
```blocks
|
|
radio.setGroup(99)
|
|
basic.forever(() => {
|
|
let level = input.lightLevel()
|
|
radio.sendNumber(level)
|
|
})
|
|
```
