Add an input block for when [button A is pressed](/reference/input/button-is-pressed),
and **move** the smiley face inside it:
```blocks
basic.showLeds(`

input.onButtonPressed(Button.A, () => {

});
```
## Step 3
Now add blocks so that when [button B is pressed](/reference/input/button-is-pressed), a smiley appears:
```blocks
basic.showLeds(`
. # . # .
. # . # .
. . . . .
# . . . #

```
Try pressing button A!
## Step 3
Now add blocks so that when [button B is pressed](/reference/input/on-button-pressed),
a frowney appears:
```blocks
input.onButtonPressed(Button.A, () => {
basic.showLeds(`

```
Try pressing ``A`` or ``B``!
## 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(`
# # . # #
# # . # #
. . . . .
. # # # .
# . . . #
`)
}
})
```
