## Step 5
## Send your heartbeats over radio!
Add a second image of a broken heart.
Do you have a second @boardname@ at hand? You could use radio and send your heartbeats to other
@boardname@ and show a heart when you receive one.
* move the code in the **forever** inside
a [on data packet received](/reference/radio/on-data-packet-received) handler.
The handler will run whenever a message is received from another @boardname@.
* use [send number](/reference/radio/send-number) and [pause](/reference/basic/pause)
to broadcast a packet of data every second.
```blocks
basic.forever(() => {
radio.sendNumber(0)
basic.pause(1000)
})
radio.onDataPacketReceived(({receivedNumber}) => {
basic.showLeds(`
. # . # .
# # # # #

basic.pause(500);

## Send your smileys over radio
Do you have a second @boardname@ at hand? You could use radio and send your smileys or frownies to other
@boardname@.
Since radio can send numbers, we decide that ``0`` is the code for displaying a smiley
and ``1`` is the code for a frowney.
Change your code as follows:
* [radio send number](/reference/radio/send-number) sends a number
to any other @boardname@ in range
* [radio on data packet received](/reference/radio/on-data-packet-received) runs code
when data is received over radio
```blocks
input.onButtonPressed(Button.A, () => {
radio.sendNumber(0)
})
input.onButtonPressed(Button.B, () => {
radio.sendNumber(1)
})
radio.onDataPacketReceived(({receivedNumber}) => {
if (receivedNumber == 0) {
basic.showLeds(`
# # . # #
# # . # #
. . . . .
# . . . #
. # # # .
`)
} else {
basic.showLeds(`
# # . # #
# # . # #
. . . . .
. # # # .
# . . . #
`)
}
})
```
