Hello friends, I hope you all are doing great. Today, I am going to share the new Photodiode Library for Proteus . An LED turns electricity into light. A photodiode does the opposite: it turns light into electricity. It is the small sensor behind remote control receivers, light meters, smoke alarms and the camera in your phone, and in the right circuit it measures light with amazing accuracy.
