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 ...

In the Arduino schematic, for some reason pin 2 on the NINA-W102 is labeled "GPIO34". At first I thought I was mistaken, and that pin 2 on the Arduino schematic really is GPIO34 on the NINA, but that ...
