Code Examples

### Example 1: Controlling RGB LED with Arduino

In this example, we will demonstrate how to control the 5V RGB LED node module using an Arduino Uno board.

```c++
const int redPin = 9;  // Pin for Red LED
const int greenPin = 10;  // Pin for Green LED
const int bluePin = 11;  // Pin for Blue LED

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

void loop() {
  // Set RGB LED to Red
  digitalWrite(redPin, HIGH);
  digitalWrite(greenPin, LOW);
  digitalWrite(bluePin, LOW);
  delay(1000);

// Set RGB LED to Green
  digitalWrite(redPin, LOW);
  digitalWrite(greenPin, HIGH);
  digitalWrite(bluePin, LOW);
  delay(1000);

// Set RGB LED to Blue
  digitalWrite(redPin, LOW);
  digitalWrite(greenPin, LOW);
  digitalWrite(bluePin, HIGH);
  delay(1000);
}
```

### Example 2: Controlling RGB LED with Raspberry Pi (Python)

In this example, we will demonstrate how to control the 5V RGB LED node module using a Raspberry Pi and Python.

```python
import RPi.GPIO as GPIO
import time

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

# Define GPIO pins for RGB LEDs
redPin = 17
greenPin = 23
bluePin = 24

# Set up GPIO pins as outputs
GPIO.setup(redPin, GPIO.OUT)
GPIO.setup(greenPin, GPIO.OUT)
GPIO.setup(bluePin, GPIO.OUT)

try:
    while True:
        # Set RGB LED to Red
        GPIO.output(redPin, GPIO.HIGH)
        GPIO.output(greenPin, GPIO.LOW)
        GPIO.output(bluePin, GPIO.LOW)
        time.sleep(1)

# Set RGB LED to Green
        GPIO.output(redPin, GPIO.LOW)
        GPIO.output(greenPin, GPIO.HIGH)
        GPIO.output(bluePin, GPIO.LOW)
        time.sleep(1)

# Set RGB LED to Blue
        GPIO.output(redPin, GPIO.LOW)
        GPIO.output(greenPin, GPIO.LOW)
        GPIO.output(bluePin, GPIO.HIGH)
        time.sleep(1)

except KeyboardInterrupt:
    GPIO.cleanup()
```

Note: In both examples, ensure that the digital control signals are connected to the corresponding GPIO pins on the microcontroller or Raspberry Pi. Additionally, make sure to use a 5V power source and a suitable current-limiting resistor for the LEDs.
