Motor

Overview

In this lesson, you will learn how to use Motor, the working principle of which is that the energized coil is forced to rotate in the magnetic field then the rotor of the motor rotates accordingly on which the pinion gear drives the engine flywheel to rotate.1

Code

Note

  • You can open the file 24-motor.ino under the path of elite-explorer-kit-main\basic_project\24-motor directly.

  • Or copy this code into Arduino IDE.

After uploading the code to the UNO board, you can choose the motor’s rotation direction by typing “A” or “B” in the serial monitor.

Code Analysis

The motor can be driven by providing a voltage difference between the copper sheets at both sides of the motor. Therefore, you only need to write 0 for the voltage of one side of the copper sheet and 5V for the other side. Modify the written analog signal value to adjust the direction and speed.

// Function to rotate the motor clockwise
void clockwise(int Speed) {
  analogWrite(motorBI, 0);
  analogWrite(motorFI, Speed);
}

// Function to rotate the motor anticlockwise
void anticlockwise(int Speed) {
  analogWrite(motorBI, Speed);
  analogWrite(motorFI, 0);
}

In this example, Serial.Read() is used to control the direction of motor.

When you type 'A' in serial monitor, there calls the clockwise (255) function to make the motor rotate with the speed of 255. Input 'B', and the motor will rotate in reverse direction.

void loop() {
  // Check if there is available data on the serial port
  if (Serial.available() > 0) {
    int incomingByte = Serial.read(); // Read incoming data

    // Determine motor direction based on user input
    switch (incomingByte) {
      case 'A':
        clockwise(255); // Rotate motor clockwise
        Serial.println("The motor rotates clockwise.");
        break;
      case 'B':
        anticlockwise(255); // Rotate motor anticlockwise
        Serial.println("The motor rotates anticlockwise.");
        break;
    }
  }

  delay(3000); // Wait for 3 seconds
  stopMotor(); // Stop the motor
}
