# Send Value
|
|
|
|
Send a [string]() and [number]() together by ``radio`` to other micro:bits.
|
|
|
|
### Parameters
|
|
|
|
* a [string](/reference/types/string) to send by radio
|
|
* a [number](/reference/types/number) to send by radio
|
|
|
|
### Simulator
|
|
|
|
This function only works on the micro:bit, not in browsers.
|
|
|
|
### Example: Broadcasting acceleration
|
|
|
|
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.
|
|
|
|
```blocks
|
|
radio.setGroup(99)
|
|
input.onButtonPressed(Button.A, () => {
|
|
radio.sendValue("acc",input.acceleration(Dimension.X))
|
|
})
|
|
```
|
|
|
|
This program receives the string and number sent by the last program.
|
|
Then it shows them on the LED screen.
|
|
|
|
```blocks
|
|
radio.setGroup(99)
|
|
radio.onDataReceived(() => {
|
|
basic.showString(radio.receiveString());
|
|
basic.showNumber(radio.receiveNumber());
|
|
});
|
|
```
|
|
|
