The KY-016 Full Color RGB LED emits a wide range of different colors by mixing red, green and blue light. Compatible with many popular microcontrollers like Arduino, Raspberry Pi and ESP32.


KY-016 Specifications
This module consists of a 5mm RGB LED, 3 150Ω limiting resistors to prevent burnout and 4 male header pins. Adjusting the PWM signal on each color pin will result on different colors.
Operating Voltage | 5V |
LED Drive Mode | Common cathode drive |
LED Diameter | 5mm |
Board Size | 15mm x 19mm [0.59in x 0.75in] |
Connection Diagram
Connect the module red pin (R) to pin 11 on the Arduino. Blue (B) to pin 10, green (G) to pin 9 and ground (-) to GND.

KY-016 Arduino Code
The following Arduino sketch will gradually increase/decrease the PWM values on the red, green and blue pins causing the LED to cycle through various colors.
int redpin = 11; // select the pin for the red LED
int bluepin =10; // select the pin for the blue LED
int greenpin =9; // select the pin for the green LED
int val;
void setup() {
pinMode(redpin, OUTPUT);
pinMode(bluepin, OUTPUT);
pinMode(greenpin, OUTPUT);
Serial.begin(9600);
}
void loop() {
for(val = 255; val > 0; val--)
{
analogWrite(11, val);
analogWrite(10, 255 - val);
analogWrite(9, 128 - val);
Serial.println(val, DEC);
delay(5);
}
for(val = 0; val < 255; val++)
{
analogWrite(11, val);
analogWrite(10, 255 - val);
analogWrite(9, 128 - val);
Serial.println(val, DEC);
delay(5);
}
}
You found that RBG module on Frizting?? Where is it? I can’t find it and I need it in my schematics.
