Arduino – (Very) Basic motion tracking with 2 PIR sensors

Took me a little while to get started but I’ve managed to wire 2 PIR infrared sensors with an Arduino to sense motion either on the left or on the right side. The result will trigger an LED to represent each PIR sensor then I also added in a servo to be controlled – so it turns left when triggered by the left sensor and so on. First have a look at my previous tutorial – Arduino PIR motion detector circuit. ...
