## 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(() => {
basic.showLeds(`
. # . # .
# # # # #
# # # # #
. # # # .
. . # . .`
);
basic.pause(500);
basic.clearScreen();
basic.pause(500);

. . # . .`
);
basic.pause(500);
basic.clearScreen();
basic.pause(500);
radio.sendNumber(0)
basic.pause(1000)
})
radio.onDataPacketReceived(({receivedNumber}) => {
basic.showLeds(`

. . # . .`);
basic.pause(500)
basic.clearScreen()
basic.pause(500)

Download the .hex file onto both @boardname@ and try it out!
