It’s clear from its name that IR Detector simply detects Infrared signals in its range due to this functionality IR Detector is very popular and widely used for so many applications like Remote control systems, motion detectors, Line Following Robots, and Alarms.
So in this tutorial, I am going to show you “How to make a very simple IR LED Detector circuit”. Check this video for more clarification.
