To turn this static image into an animation, we need another block to place just under the
show leds

The block is just what it says; it tells the micro:bit to pause and wait for a certain amount of

The reason we are using two and placing one at the end is that this program is a loop. Without the
block at the end, the image in your animation will change really, really fast.
