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:
This is a more real-life representation of it:
Congratulations, you now know how to make a buzzer buzz.
