Buzzer Driver Circuit Diagram. With sw1 positioned as shown in the circuit diagram it reproduces the typical dual tone sound of police contact. The only problem being that the voltage available is only 1 5v.
1 ic 2 tones siren double tone police sound single tone old am bulance sound this circuit is intended for children fun and is suitable to be installed on bicycles battery powered cars and motorcycles but also in models and other games. The buzzer may operate at 9v 12v or some other voltage. This article and circuit diagram show how to connect a buzzer to an arduino when the buzzer operates at a different voltage to the arduino.
Simple magnetic buzzer circuit with um66 ic simple piezo buzzer circuit with um66t ic simple piezo buzzer circuit diagram and project details.
A piezo buzzer acts very similar to a capacitor and needs a push pull driver circuit to charge and then discharge the capacitance of the piezo. All the voltages referred to here are d c. In addition to this a siren or 555 tone generators can be interchangeably used as a buzzer. Flavio dellepiane fladello tin it.
