In this tutorial we will check how to create a very simple alarm system with a buzzer and a PIR motion sensor. We will be using the Arduino core, running on the ESP32. The tests were performed using a DFRobot’s ESP32 module integrated … Continue reading
The objective of this code is to explain how to control a buzzer with the ESP32, using its PWM functionalities. In particular, we are going to use ESP32’s LED PWM functions.
