This project demonstrates how to use a buzzer module with an Arduino Nano to produce sound or generate alerts. Buzzer modules can be either active or passive, each requiring different driving methods.

How to use a Passive buzzer with Arduino? The Passive Buzzer connection to the Arduino is exactly the same as what we’ve done with the Active Buzzer. We can use a PWM output pin to control the passive ...

The point was to learn how to take the most basic circuit connected to an active or passive buzzer and generate musical notes by toggling the circuit HIGH/LOW, and then see how effectively chords ...
