PWM control modules are ideal for Arduino projects, robotics, and applications where precise motor speed control is required. You can use it to create small-scale transportation systems or integrate it into devices that require accurate power regulation.

Tutorial: How to use DC Motor PWM Control Module

This module allows you to control the speed and operation of low-power DC motors up to 90W. Ideal for Arduino projects, robotics, or any application that requires precise motor speed control.

What you need

• Arduino Uno
• DC Motor Compatible
• Connection Cables

Steps

1. Connect the VCC and GND pins of the module to the 5V and GND bus of the Arduino.
2. Connect the PWM (Speed) pin of the module to a digital output pin of the Arduino.
3. If necessary, connect the IN1 and IN2 pins for motor direction to digital pins of the Arduino.
4. Check that the motors are compatible with the module’s power supply (5V-35V).
5. Write an Arduino sketch to control the motor through the connected PWM pin.
6. Test the motor direction and speed by modifying the values in the Arduino code.
7. Adjust the external power supply if necessary (5V-35V).
8. Monitor the temperature during use to ensure the module does not exceed its thermal dissipation capabilities.

Example code

void setup() {
  pinMode(9, OUTPUT);
}

void loop() {
  analogWrite(9, 128); // Setta la velocità del motore a metà.
}
