This tutorial shows you how to use the YYNMOS-4 4 Channel MOSFET Module to control intensity of LIGH or speed of 4 motors. Module is explained, Arduino code explained and testd.
/*
* This is Arduio code to control 4 DC motor's speed or 4 LED light strip or other DC load
* buy utilizing YYNMOS-4 4 channel mosfet module
We can control 4 DC Motors with voltage of 5V to 35V and 5A each.
