## Example: diagonal line
|
|
|
|
The following example uses a while loop to make a diagonal line on the LED screen (points `0, 0`, `1, 1`, `2, 2`, `3, 3`, `4, 4`).
|
|
|
|
```blocks
|
|
input.onButtonEvent(Button.A, input.buttonEventValue(ButtonEvent.Down), () => {
|
|
let index = 4;
|
|
while(index >= 0) {
|
|
led.plot(index, index);
|
|
index--;
|
|
}
|
|
})
|
|
```
