  // Change the motor speed
  motorSpeed = 200; // 80% duty cycle
  analogWrite(pwmPin, motorSpeed);

### Example 2: Motor Speed Control with Raspberry Pi (Python)
In this example, we will use the 12V 10A PWM DC Motor Speed Controller to control the speed of a DC motor using a Raspberry Pi board.
```python
import RPi.GPIO as GPIO
import time
# Set up GPIO mode
GPIO.setmode(GPIO.BCM)
# Define the PWM and enable pins
pwmPin = 18
enPin = 23
# Set up the pins as outputs
GPIO.setup(pwmPin, GPIO.OUT)
GPIO.setup(enPin, GPIO.OUT)
# Enable the motor controller
GPIO.output(enPin, GPIO.HIGH)
try:
    while True:
        # Set the motor speed using PWM (0-100%)
        motorSpeed = 50  # 50% duty cycle
        GPIO.output(pwmPin, GPIO.HIGH)
        time.sleep(motorSpeed / 100)
        GPIO.output(pwmPin, GPIO.LOW)
        time.sleep((100 - motorSpeed) / 100)
        
        # Change the motor speed
        motorSpeed = 80  # 80% duty cycle
        GPIO.output(pwmPin, GPIO.HIGH)
        time.sleep(motorSpeed / 100)
        GPIO.output(pwmPin, GPIO.LOW)
        time.sleep((100 - motorSpeed) / 100)
except KeyboardInterrupt:
    # Clean up GPIO on exit
    GPIO.cleanup()
```
