Cách sử dụng Mosfet Optocoupled HW-532 để điều khiển tốc độ động cơ DC lên đến 30V hoặc tải bằng Arduino

/* 
* Lesson 108-1: In this lesson we learn how to use  the module with FR120N , LR7843 and D4184 MOSFET to turn ON/OFF DC load up to up to 10A. HW-532 optically isolated from 5V to 30V load up to 10A depending on the module. Schematic shown, wiring diagram explained, different 
method of wiring with push button and potentiometer also shown.
