Brushed DC Motor Speed Controller Using Radio Control (RC) Remote
This is a Brushed DC motor controller designed to control one brushed DC motor up to 5A. It can control the speed of the DC motor using a Radio Control (RC) System. This Arduino compatible hardware converts RC PWM signal into 0 to 100% duty cycle PWM which further drives high current load using MOSFET. The project consists of an Atmega328 microcontroller, and a gate driver optocoupler provides isolation between MOSFET and microcontroller circuit to prevent high voltage and noise traveling from the motor and related circuit to the microcontroller. The circuit can drive a motor up to 5A with a power supply of 12V to 40V DC. The board has the option to mount higher voltage and current MOSFET, which can drive higher Voltage and current load. In this case don’t install Q2, install Q1 MOSFET FDH3632, and replace diode D2 with a higher current diode.
