Hi guys in this project I shall show you that how you can make a RGB Light cntoller. Here is the PCB layout

PCB Layout :

Arduino Code :

//Bluetooth Controlled Arduino RGB Led Strip//

#include <SoftwareSerial.h>

SoftwareSerial BLU(0,1);

#define redPin A1

#define greenPin A2

#define bluePin A0

void setup()

{

//Serial setup

Serial.begin(9600);

Serial.println("-= HC-05 Bluetooth RGB LED =-");

BLU.begin(9600);

BLU.println("-= HC-05 Bluetooth RGB LED =-");

pinMode(redPin, OUTPUT);

pinMode(greenPin, OUTPUT);

pinMode(bluePin, OUTPUT);

setColor(255, 0, 0);

delay(500);

setColor(0, 255, 0);

delay(500);

setColor(0, 0, 255);

delay(500);

setColor(255, 255, 255);

}

void loop()

{

while (BLU.available() > 0)

{

int redInt = BLU.parseInt();

int greenInt = BLU.parseInt();

int blueInt = BLU.parseInt();

redInt = constrain(redInt, 0, 255);

greenInt = constrain(greenInt, 0, 255);

blueInt = constrain(blueInt, 0, 255);

if (BLU.available() > 0)

{

setColor(redInt, greenInt, blueInt);

Serial.print("Red: ");

Serial.print(redInt);

Serial.print(" Green: ");

Serial.print(greenInt);

Serial.print(" Blue: ");

Serial.print(blueInt);

Serial.println();

BLU.flush();

}

}

}

void setColor(int red, int green, int blue)

{

analogWrite(redPin, red);

analogWrite(greenPin, green);

analogWrite(bluePin, blue);

}
