In this tutorial we will check how to interact with a PIR motion sensor using an interrupt based approach, using theArduinocore running on the ESP32. In the previous tutorial, we covered the basics on how to interact with the PIR sensor. Nonetheless, we followed a polling approach, which i...
PIR Sensor for your Arduino APIRor Passive Infrared module is really fun to play with. This is what they look like: They are basically a motion detector and are called ‘passive’ in the sense that these devices do not generate any energy for detection purposes. They work entirely by detect...
