A buzzer will produce a single audible tone when a voltage is applied and current passes through it. To play different tones or musical tunes consider using the piezo instead.

Activate a buzzer

The following program will activate a FET or Darlington transistor connected to output B.1, which in turn will sound the buzzer, for a second every five seconds.

Code Example:
main: 	high B.1 	; Switch on output B.1 
	pause 1000 	; Wait 1 second 
	low B.1 	; Switch off output B.1 
	pause 5000 	; Wait 5 seconds 
	goto main 	; Loop back to start
