Theoretically, LED Can Act as Light Emitter & Light Detector. Here is How To Use LED as Sensor For Arduino, Circuit & Code Explaining Sensors in Robotics. This plain LED is never used in real life as sensor as basically they are designed to emit light, the light sense works better in one direction, sensitivity is lesser. This is analog sensor. First, we are sharing the code & circuit … [Read more...]
