The buzzer, a firm favourite amongst children everywhere, is a relatively simple component to use. It only requires two connections, one from a + output, and one to a – input.

The + on the buzzer needs to connect to an output on the Crumble (A, B, C or D) and the other end needs to connect to a – input. It is even possible to use the motor outputs if you wish.

Note: Don’t forget you will need to add batteries.
