Buy this sensor or kit.


Overview

RGB LED module consists of a plug-in full color LED made by R, G, B three pin PWM voltage input can be adjusted Section three primary colors (red / blue / green) strength in order to achieve full color mixing effect. Control of the module with the Arduino can be achieved Cool lighting effects.

Specifications

  • the use of plug-in full-color LED
  • RGB trichromatic limiting resistor to prevent burnout
  • through the PWM adjusting three primary colors can be mixed to obtain different colors
  • with a variety of single-chip interface
  • the working voltage: 5V
  • LED drive mode: common cathode driver


Schematic

  • Arduino pin 11 --> Pin R module
  • Arduino pin 10 --> Pin G module
  • Arduino pin 9 --> Pin B module
  • Arduino pin GND --> Pin - module

You don't need any resistors, these are already included on the module.

Example code

//KY016 3-color LED module
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);
    delay (10);
    Serial.println (val, DEC);
  }
  for (val = 0; val <255; val ++)
  {
    analogWrite (11, val);
    analogWrite (10, 255-val);
    analogWrite (9, 128-val);
    delay (10);
    Serial.println (val, DEC);
  }
}

/*
 Demo for KY-009 and KY-016.
 Plug the board directly in your Arduino board without using
 cables. If you turn the board 180° you should use pin 12 as
 ground and swap the green and blue pin.
 The demo will over time cycle through all the 16777216
 different colors which can be made with 3x8bit.
