Other Arduino Codes and Videos by Robojax
This article is on how to use the E-Switch module based on IRF5305 MOSFET module. This module can act as a switch and can be controlled as motor speed controller. All aspects of this module has been explained in the provided video at Robojax.com. 3 different codes has been provided for different usage of this. Also we have tested the module to see how much current it can handle under HIGH (24V) and at Low (5V).
Image above shows Mosfet used as switch.
Image above shows MOSFET used to control a load connected at Drain pin.
Image above shows MOSFET used to control a load connected at Source pin.
