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);
}
