Buzzer
Buggy Base contains a Buzzer capable of producing sounds. When pulses of electricity are sent to the Buzzer, the pulses causes the Buzzer to vibrate and produce an audible sound. Pulses of different frequencies will cause the Buzzer to produce different notes. The following blocks will allow the user to control the Buzzer.
Block: Play Note
