How To Make A Buzzer Circuit

how to make a buzzer circuit

Simple Water Heater Alarm Circuit homemade-circuits.com

A buzzer can produce a chirping noise if you charge a capacitor and then allow the capacitor to discharge into the buzzer. Because the voltage of the capacitor becomes less and less as time elapses when it discharges, it feeds different voltages into the buzzer. The differing voltage levels produce

In this project, we will go over how to build a dark-activated buzzer circuit. This is a circuit in which a buzzer will sound when it is dark in the ambient environment. As soon as there ambient darkness is sensed by the circuit, the buzzer will automatically turn on and remain on as long as the darkness remains. The component that allows for the light sensing in this circuit is a

1. You wouldn't normally run a transistor with no current limit into the base. Usually, a transistor switch is run with a beta of 10, so if your collector current is 90mA, your base current needs to be 9mA or so, which would make the base resistor about 240 ohms if your base drive is 3.3 volts.
