# On Data Received
> Note: This API has been deprecated! Use [on data packet received](/reference/radio/on-data-packet-received) instead.
Run part of a program when the @boardname@ receives a
[number](/reference/types/number) or [string](/reference/types/string) over ``radio``.
```sig
radio.onDataReceived(() => { });
```
### Example
This program keeps sending numbers that says how fast the @boardname@ is
slowing down or speeding up. It also receives numbers for the same
thing from nearby @boardname@s. It shows these numbers as a
[bar graph](/reference/led/plot-bar-graph).
```blocks
basic.forever(() => {
radio.sendNumber(input.acceleration(Dimension.X));
})
radio.onDataReceived(() => {
led.plotBarGraph(radio.receiveNumber(), 1023);
})
```
