Optocoupler as a Switch trick #Shorts
In this project, I’ve used an 817 optocoupler as a switch to control an LED using two push buttons. The upper button turns the LED ON, and the lower one turns it OFF — a simple yet smart way to understand how optocouplers work for isolation and control. It runs directly from a 3.7V battery and is great for beginners learning electronics and ...
