3 Pieces RGB Multicolor 5mm Common Anode LED 8000mcd

Description

📌 Complete description of the RGB MULTICOLOR 5mm COMMON ANODE 8000mcd LED MODULE

The RGB 5mm common anode 8000mcd LED is an electronic component capable of emitting light red, green and blue from a single package (housing), combining the three primary colors to achieve a wide range of colors. The term “common anode” means that the positive terminal (anode) of the three internal LEDs is shared, while each cathode (negative terminal) is separate for each color.

⚙️ Technical specifications

Characteristic	Value
LED Type	RGB 5mm Common Anode
Luminous Intensity	Approximately 8000 mcd (high brightness)
Colors	Red, Green, Blue (can be combined into many others)
Nominal Current	20 mA per each color
Direct Current Voltage (Typical)	Red: 2.0V – Green: 3.2V – Blue: 3.2V
Pin Configuration	4 pins (1 common, 3 for the colors)
Emission Angle	~30-40°
Control Type	PWM (Pulse Width Modulation)

⚠ Note: being a common anode LED, the common pin should be connected to +5V, and each color is activated by sending LOW (0V) to its respective pin through a resistor and an Arduino output pin.

🧑‍💻 Example code for Arduino

1️⃣ Turn on one color at a time

int redPin = 9;
int greenPin = 10;
int bluePin = 11;

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

void loop() {
 digitalWrite(redPin, LOW); // Rosso acceso
 digitalWrite(greenPin, HIGH);
 digitalWrite(bluePin, HIGH);
 delay(1000);

 digitalWrite(redPin, HIGH);
 digitalWrite(greenPin, LOW); // Verde acceso
 digitalWrite(bluePin, HIGH);
 delay(1000);

 digitalWrite(redPin, HIGH);
 digitalWrite(greenPin, HIGH);
 digitalWrite(bluePin, LOW); // Blu acceso
 delay(1000);
}

2️⃣ Mix colors with PWM

int redPin = 9;
int greenPin = 10;
int bluePin = 11;

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

void loop() {
 setColor(255, 0, 0); // Rosso
 delay(1000);
 setColor(0, 255, 0); // Verde
 delay(1000);
 setColor(0, 0, 255); // Blu
 delay(1000);
 setColor(255, 255, 0); // Giallo
 delay(1000);
 setColor(0, 255, 255); // Ciano
 delay(1000);
 setColor(255, 0, 255); // Magenta
 delay(1000);
 setColor(255, 255, 255); // Bianco
 delay(1000);
 setColor(0, 0, 0); // Spento
 delay(1000);
}

void setColor(int red, int green, int blue) {
 analogWrite(redPin, 255 - red);
 analogWrite(greenPin, 255 - green);
 analogWrite(bluePin, 255 - blue);
}

🧠 Note on the function setColor(): since the LED is at common anode, PWM values must be inverted: 0 = fully on, 255 = off.

💡 Usage Tips

• Use PWM (through analogWrite) to create fade or color cycle effects.
• For more realistic colors, consider the different intensities of each LED: blue and green are generally brighter than red.
• You can create rainbow or animation effects by cycling through RGB values progressively.

---

🧪 Example: Rainbow Fade Effect

void loop() {
 for (int r = 0; r <= 255; r += 5) {
 setColor(r, 0, 255 - r); // Dal blu al rosso
 delay(30);
 }

 for (int g = 0; g <= 255; g += 5) {
 setColor(255 - g, g, 0); // Dal rosso al verde
 delay(30);
 }

 for (int b = 0; b <= 255; b += 5) {
 setColor(0, 255 - b, b); // Dal verde al blu
 delay(30);
 }
}
