Code Examples
### Example 1: Arduino Uno Control with Potentiometer
In this example, we will use an Arduino Uno to control the motor speed using the built-in potentiometer.
```cpp
const int potPin = A0;  // Potentiometer connected to analog input A0
const int pwmPin = 9;  // PWM output connected to digital pin 9
void setup() {
  pinMode(pwmPin, OUTPUT);
}
void loop() {
  int potValue = analogRead(potPin);
  int pwmValue = map(potValue, 0, 1023, 0, 255);
  analogWrite(pwmPin, pwmValue);
  delay(10);
}
```
In this code, we read the analog value from the potentiometer and map it to a PWM value between 0 and 255. We then write the PWM value to the digital pin connected to the motor speed controller's PWM input.
### Example 2: Raspberry Pi Control with Python
In this example, we will use a Raspberry Pi to control the motor speed using Python and the RPi.GPIO library.
```python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
pwm_pin = 18  # PWM output connected to GPIO 18
GPIO.setup(pwm_pin, GPIO.OUT)
pwm_frequency = 50
pwm = GPIO.PWM(pwm_pin, pwm_frequency)
while True:
    for dc in range(0, 101, 1):
        pwm.ChangeDutyCycle(dc)
        time.sleep(0.01)
    for dc in range(100, -1, -1):
        pwm.ChangeDutyCycle(dc)
        time.sleep(0.01)
```
In this code, we set up the PWM output on GPIO 18 and create a PWM object with a frequency of 50 Hz. We then create a loop that varies the duty cycle of the PWM signal from 0 to 100% and back to 0, effectively creating a speed ramp.
Note: Make sure to adjust the pin connections and frequencies according to your specific setup and requirements.
