 These small devices play a high-pitched bleep when connected to a circuit. To
 attach one to your BBC micro:bit you should attach crocodile clips to pin 0 and
 GND (as shown below).

 sleeps for twenty milliseconds and then switches pin 0 off. This gives the
 effect of a short bleep. Finally, the device sleeps for 480 milliseconds before
 looping back and starting all over again. This means you'll get two bleeps per
 second (one every 500 milliseconds).
