# 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))
})
```
