Product Description

1. 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.

      
2. Product Features:
         

1>. the use of plug-in full-color LED
         

2>. RGB trichromatic limiting resistor to prevent burnout
         

3>. through the PWM adjusting three primary colors can be mixed to obtain different colors
         

4>. with a variety of single-chip interface
         

5>. the working voltage: 5V
         

6>. LED drive mode: common cathode driver

      
3. Arduino test code:

      
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(1);
          }
          for (val = 0; val <255; val++)
          {
          analogWrite(11, val);
          analogWrite(10, 255-val);
          analogWrite(9, 128-val);
          delay (1);
          }
          Serial.println(val, DEC);
          }
