Use buttons to show a smiley face!
|
|
|
|
### ~
|
|
|
|
## Step 1
|
|
|
|
Use [show leds](/reference/basic/show-leds) to make a smiley face:
|
|
|
|
```blocks
|
|
basic.showLeds(`
|
|
# # . # #
|
|
# # . # #
|
|
. . . . .
|
|
# . . . #
|
|
. # # # .`
|
|
);
|
|
```
|
|
|
|
## Step 2
|
|
|
|
Add an input block for when [button A is pressed](/reference/input/button-is-pressed),
|
|
and **move** the smiley face inside it:
|
|
|
|
```blocks
|
|
input.onButtonPressed(Button.A, () => {
|
|
basic.showLeds(`
|
|
# # . # #
|
|
# # . # #
|
|
. . . . .
|
|
# . . . #
|
|
. # # # .`
|
|
);
|
|
});
|
|
```
|
|
|
|
Try pressing button A!
|
|
|
|
## Step 3
|
|
|
|
Add blocks so that when [button B is pressed](/reference/input/on-button-pressed),
|
|
a frowney appears:
|
|
|
|
```blocks
|
|
input.onButtonPressed(Button.A, () => {
|
|
basic.showLeds(`
|
|
# # . # #
|
|
# # . # #
|
|
. . . . .
|
|
# . . . #
|
|
. # # # .`
|
|
);
|
|
});
|
|
input.onButtonPressed(Button.B, () => {
|
|
basic.showLeds(`
|
|
# # . # #
|
|
# # . # #
|
|
. . . . .
|
|
. # # # .
|
|
# . . . #`
|
|
);
|
|
});
|
|
```
|
|
|
|
Try pressing ``A`` or ``B``!
|
|
|
|
## Step 4
|
|
|
|
You can also have a secret mode where ``A`` and ``B`` are pressed together.
|
|
In that case, add multiple ``||show leds||`` blocks to create an animation...
|
|
|
|
```blocks
|
|
input.onButtonPressed(Button.AB, () => {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
# . . . #
|
|
. # # # .
|
|
`)
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
# # # # #
|
|
. . . . .
|
|
`)
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
. # # # .
|
|
# . . . #
|
|
`)
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. # . # .
|
|
. . . . .
|
|
# # # # #
|
|
. . . # #
|
|
`)
|
|
basic.showLeds(`
|
|
. . . . .
|
|
# . # . .
|
|
. . . . .
|
|
# . . . #
|
|
. # # # .
|
|
`)
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . # . #
|
|
. . . . .
|
|
# . . . #
|
|
. # # # .
|
|
`)
|
|
})
|
|
```

## 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(`
|
|
# # . # #
|
|
# # . # #
|
|
. . . . .
|
|
. # # # .
|
|
# . . . #
|
|
`)
|
|
}
|
|
})
|
|
```
|
|
|
|
```package
|
|
radio
|
|
```
