This project demonstrates how to interface a PIR (Passive Infrared) motion sensor with an Arduino Uno R3 to detect movement and trigger an LED. When the PIR sensor detects motion, the LED turns on for ...
This application note describes how to use the 12-bit differential ADC with PGA in the tinyAVR® 2 Family of microcontrollers and how to collect measurements using a Passive InfraRed (PIR) sensor while ...
