Part 5: DC Motors

Using this code we can control speed of motor using Arduino by using 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.

<>Using this moduel we can't control direction of rotation of the motor.

Projects

In Project 2 We Control speed of the motor using Arduino code.
