RGB Amplifier 4A/Ch for interfacing with a Micro-Controller (PWM/TTL Input)

For Controlling RGB or 1-3x single color flex strips with a Micro-Controller

Great for an easy way to control your lights with custom software or via timers, motion detectors, home automation software, internet or iPhone

For instructions visit Fritzing.org or you can search http://www.arduino.cc for PWM and/or RGB for software and instructions

In your program you will want to write (ledPin, LOW); to turn on the device and (ledPin, HIGH); to turn it off

~~For 12V DC LED Strips or other 12v DC Devices like: relays, motors, lights, valves or anything that needs on/off or PWM Switching of 1-3 channels
~~Input Voltage: 2.0v - 5.5v (suggested) (+) is common and each of the 3 channels have separate (-)
~~Output:  Common (+) Anode  (you can use 1, 2 or all 3 of the channels)
These units will turn on the 12v output with a input voltage of  2.0 volts or higher

follow the instructions in this picture then write to your output Pins to control the lights/devices
Arduino Code
analogWrite(PinX, 255)       // = Off   (for 0--100% (PWM) LED Lights)
analogWrite(PinX, 0)           // = On   (for  0--100% (PWM) LED Lights)
or
digitalWrite(PinX, HIGH); // = Off    (for Relays or Lights with just on/off control)
digitalWrite(PinX, LOW); // = On      (for Relays or Lights with just on/off control)

Here are some code examples

                                   // by Desta Courtney      www.usLEDsupply.com
int BluePin = 9;                   // Digital Pin 9 Connected to B on Amp

int GreenPin = 10;                 // Digital Pin 10 Connected to G on Amp

int RedPin = 11;                   // Digital Pin 11 Connected to R on Amp

int a = 1200;     // Blue on Time
int b = 0;
int c = 1200;     // Green on Time
int d = 0;
int e = 1200;     // Red on Time
int f = 0;
int g = 1200;     // Yellow on Time
int h = 0;
int i = 1200;     // Light Blue on Time
int j = 0;
int k = 1200;     // Puple on Time
int l = 0;
int x = 240;     // Sets On Level 0 = 100% (Lower Number will be brighter)
int y = 255;     // Sets Off Level 255 = 0% (Higher Number will be dimmer)

void setup()
{
  pinMode(BluePin, OUTPUT);      // sets the digital pin as output
  pinMode(GreenPin, OUTPUT);      // sets the digital pin as output
  pinMode(RedPin, OUTPUT);      // sets the digital pin as output
  analogWrite(BluePin, y);
  analogWrite(GreenPin, y);
  analogWrite(RedPin, y);
  
}

void loop()
{
    analogWrite(BluePin, x);
    delay(a);
    analogWrite(BluePin, y);
     
    delay(b);  
    
    analogWrite(GreenPin, x);
    delay(c);
    analogWrite(GreenPin, y);
    
    delay(d);
    
    analogWrite(RedPin, x);
    delay(e);
    analogWrite(RedPin, y);
    
    delay(f);
    
    analogWrite(BluePin, x);
    analogWrite(GreenPin, x);
    delay(g);
    analogWrite(BluePin, y);
    analogWrite(GreenPin, y);
    delay(h);
    
    analogWrite(RedPin, x);
    analogWrite(GreenPin, x);
    delay(i);
    analogWrite(RedPin, y);
    analogWrite(GreenPin, y);
    delay(j);
    
    analogWrite(BluePin, x);
    analogWrite(RedPin, x);
    delay(k);
    analogWrite(BluePin, y);
    analogWrite(RedPin, y);
    delay(l);
    

}

Simply connect the 3x PWM output pins of your Micro-Controller to the RGB input of this amp then connect the (+) input to the +5v output on your Micro-Controller. 

Then, connect a 12v DC power supply to the (+) and (-) inputs on the amp and connect your RGB LED strips to the Output.
