It’s important to set up stop animation before showing the
animation, so the stop animation part of the program will be ready
to go.
Stop the animation that is playing and any animations that are waiting to play.
led.stopAnimation()This program sets up the stop animation part of the program,
and then shows a string that you can stop with button B.
input.onButtonPressed(Button.B, () => {
led.stopAnimation();
});
basic.showString("STOP ME! STOP ME! PLEASE, WON'T SOMEBODY STOP ME?");
