ESP32 Arduino: Alarm with PIR motion sensor and buzzer ...

· 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. Basically, when motion is detected by the PIR sensor, we will trigger the buzzer to start emitting a loud sound. When the sensor stops detecting motion, then we stop the buzzer.
