This tutorial gives an introduction to the HY-M154 / 817 optocoupler module. Moreover, a simple application is programmed that shows how to wire and how to program an Arduino when
1. What is the PC817? The PC817 consists of an infrared LED and a phototransistor in a 4-pin package. It isolates low-voltage control circuits (e.g., Arduino, ESP32, STM32) from high-voltage power
It allows signal transmission without a direct electrical connection. Inside, it combines an infrared LED and a phototransistor, enabling signals to pass through light. This setup provides safety and protects
The phototransistor base is stimulated by light received from a light emitting diode and can pass current according to it. Opto-couplers are used where two circuits need to be separated
