The Connections are pretty simple: Connect the Supply wire (RED) of the buzzer to the Digital Pin 9 of the Arduino through a 100-ohm resistor. Connect the Ground wire (BLACK) of the buzzer to any Ground Pin on the Arduino.
How many volts is a buzzer?
Working voltage: the working voltage of the electromagnetic buzzer can be 1.5-24 V, and the working voltage range of the piezoelectric buzzer can be 3v-220v. However, under normal circumstances, the working voltage range of the piezoelectric buzzer is recommended to be above 9V to obtain a larger sound.
