## 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.onButtonPressed(Button.A, () => {
|
||||
let index = 4;
|
||||
while(index >= 0) {
|
||||
led.plot(index, index);
|
||||
index--;
|
||||
}
|
||||
})
|
||||
```
