Code Examples

### Example 1: Basic RGB LED Control using Arduino

In this example, we'll demonstrate how to control the RGB LED using an Arduino board. We'll connect the LED to digital pins 9, 10, and 11, and use the `analogWrite()` function to set the brightness of each color channel.
```cpp
const int redPin = 9;    // Red cathode (Pin 2)
const int greenPin = 10; // Green cathode (Pin 3)
const int bluePin = 11;  // Blue cathode (Pin 4)

void setup() {
  pinMode(redPin, OUTPUT);
  pinMode(greenPin, OUTPUT);
  pinMode(bluePin, OUTPUT);
}

void loop() {
  // Set RGB values from 0 (off) to 255 (maximum brightness)
  analogWrite(redPin, 128);  // Half-bright red
  analogWrite(greenPin, 255); // Full-bright green
  analogWrite(bluePin, 0);   // Off blue

delay(1000); // Wait 1 second

// Change the RGB values
  analogWrite(redPin, 0);
  analogWrite(greenPin, 128);
  analogWrite(bluePin, 255);

delay(1000); // Wait 1 second
}
```
### Example 2: RGB LED Color Fading using Raspberry Pi (Python)

In this example, we'll demonstrate how to control the RGB LED using a Raspberry Pi and Python. We'll use the RPi.GPIO library to control the GPIO pins, and create a color-fading effect by incrementing the brightness of each color channel.
```python
import RPi.GPIO as GPIO
import time

# Set up GPIO pins
GPIO.setmode(GPIO.BCM)

redPin = 17
greenPin = 23
bluePin = 24

GPIO.setup(redPin, GPIO.OUT)
GPIO.setup(greenPin, GPIO.OUT)
GPIO.setup(bluePin, GPIO.OUT)

# Define RGB color values (0-255)
r, g, b = 0, 0, 0

while True:
  # Fade red
  for i in range(256):
    GPIO_output(redPin, i)
    time.sleep(0.01)

# Fade green
  for i in range(256):
    GPIO_output(greenPin, i)
    time.sleep(0.01)

# Fade blue
  for i in range(256):
    GPIO_output(bluePin, i)
    time.sleep(0.01)
```
These examples demonstrate the basic principles of controlling an RGB LED using an Arduino board and a Raspberry Pi, respectively. You can modify the code to create various color effects, patterns, and animations.
