How to Build a Buzzer Circuit

How to Build a Buzzer Circuit

Now shown is the simplest, easiest circuit that you can build to make a buzzer circuit work, making it do what supposed to do: buzz!


Components Needed

9-volt Battery
Buzzer

In this project, all we do is hook up the positive side of the battery to the positive lead of the buzzer and the negative side of the battery to the negative lead of the buzzer. The positive lead of the buzzer many of the times is a red color and the negative lead of the buzzer is usually a black color.



This is the schematic of the circuit that we've built:
