Use buttons to show a smiley or frowny face.
|
||
|
|
|
||
|
|
## Step 1
|
||
|
|
|
||
|
|
Use [show leds](/reference/basic/showLeds) 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 put a
|
||
|
|
frowny face inside it:
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
basic.showLeds(`
|
||
|
|
. # . # .
|
||
|
|
. # . # .
|
||
|
|
. . . . .
|
||
|
|
# . . . #
|
||
|
|
. # # # .`);
|
||
|
|
input.onButtonPressed(Button.A, () => {
|
||
|
|
basic.showLeds(`
|
||
|
|
. # . # .
|
||
|
|
. # . # .
|
||
|
|
. . . . .
|
||
|
|
. # # # .
|
||
|
|
# . . . #`);
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
## Step 3
|
||
|
|
|
||
|
|
Now add blocks so that when [button B is pressed](/reference/input/button-is-pressed), a smiley appears:
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
basic.showLeds(`
|
||
|
|
. # . # .
|
||
|
|
. # . # .
|
||
|
|
. . . . .
|
||
|
|
# . . . #
|
||
|
|
. # # # .`);
|
||
|
|
input.onButtonPressed(Button.A, () => {
|
||
|
|
basic.showLeds(`
|
||
|
|
. # . # .
|
||
|
|
. # . # .
|
||
|
|
. . . . .
|
||
|
|
. # # # .
|
||
|
|
# . . . #`);
|
||
|
|
});
|
||
|
|
input.onButtonPressed(Button.B, () => {
|
||
|
|
basic.showLeds(`
|
||
|
|
. # . # .
|
||
|
|
. # . # .
|
||
|
|
. . . . .
|
||
|
|
# . . . #
|
||
|
|
. # # # .`);
|
||
|
|
});
|
||
|
|
```
