3. Connect the motor driver control pins to Arduino’s PWM pins.
4. Write and upload the Arduino sketch for motor driver control.
5. Test the motor driver’s operation with the uploaded sketch.
6. Adjust the motor driver’s speed through the Arduino code.
7. Check the motor’s operation under load.
8. Add a position sensor for precise motion control.

Example code

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

void loop() {
  analogWrite(9, 128); // Imposta la velocità del motoriduttore
}

Mini project

Basic robot with a 25GA370 gearmotor: build a small robot that moves forward and backward using a servo for direction and the 25GA370 gearmotor for propulsion. You can add a distance sensor to avoid obstacles.

Common mistakes

• Do not check the power supply voltage before connecting the gearmotor.
• Do not use a current filter to protect the circuit.
• Do not check the correct rotation of the gearmotor before mounting it.
• Do not add a position sensor for precise motion control.
