Course Introduction

This Arduino project controls a DC motor using a TA6586 motor driver and three push buttons. The blue button runs the motor at full speed in reverse, the yellow button runs it at half speed in reverse, and the red button stops the motor. The system uses PWM control to adjust speed and responds immediately to button input.

Note

If this is your first time working with an Arduino project, we recommend downloading and reviewing the basic materials first.

Don’t forget to select the board(Arduino UNO R4) and the correct port before clicking the Upload button.

// Control a motor using TA6586 driver and three buttons
// Blue button: full speed (reverse direction)
// Yellow button: half speed (reverse direction)
// Red button: stop

const int fiPin = 5;     // Forward Input pin of TA6586
const int biPin = 6;     // Backward Input pin of TA6586

const int blueBtn = 9;   // Blue button pin - full speed
const int yellowBtn = 10;// Yellow button pin - half speed
const int redBtn = 11;   // Red button pin - stop

void setup() {
  // Set motor control pins as outputs
  pinMode(fiPin, OUTPUT);
  pinMode(biPin, OUTPUT);

  // Set button pins as inputs with internal pull-up resistors
  // (HIGH when not pressed, LOW when pressed)
  pinMode(blueBtn, INPUT_PULLUP);
  pinMode(yellowBtn, INPUT_PULLUP);
  pinMode(redBtn, INPUT_PULLUP);
}

void loop() {
  // When the blue button is pressed: full speed reverse
  if (digitalRead(blueBtn) == LOW) {
    analogWrite(biPin, 255);  // Full speed reverse
    analogWrite(fiPin, 0);    // Stop forward output
  }
  // When the yellow button is pressed: half speed reverse
  else if (digitalRead(yellowBtn) == LOW) {
    analogWrite(biPin, 128);  // Half speed reverse
    analogWrite(fiPin, 0);
  }
  // When the red button is pressed: stop the motor
  else if (digitalRead(redBtn) == LOW) {
    analogWrite(biPin, 0);
    analogWrite(fiPin, 0);
  }
}
