enable_pin = 17  # Connect to IN1
direction_pin = 23  # Connect to IN2
pwm_pin = 18  # Connect to PWM

GPIO.setup(enable_pin, GPIO.OUT)
GPIO.setup(direction_pin, GPIO.OUT)
GPIO.setup(pwm_pin, GPIO.OUT)

pwm = GPIO.PWM(pwm_pin, 20)  # 20 kHz PWM frequency

try:
    while True:
        # Enable the motor
        GPIO.output(enable_pin, GPIO.HIGH)
        
        # Set the motor direction (forward)
        GPIO.output(direction_pin, GPIO.HIGH)
        
        # Set the motor speed to 50%
        pwm.start(50)
        
        time.sleep(2)
        
        # Change the motor speed to 75%
        pwm.ChangeDutyCycle(75)
        
        time.sleep(2)
        
        # Disable the motor
        GPIO.output(enable_pin, GPIO.LOW)
