# 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.
## Example: 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 data packet received](/reference/radio/on-data-packet-received) example.
```blocks
radio.setGroup(99)
basic.forever(() => {
let level = input.lightLevel()
radio.sendNumber(level)
})
```
