Pretty Light

You can change the light of the RGB LED by using the smart phone

RGB LED have a 7 colours so this project makes a very cool light

-Arduino

-Breadboard

-Bluetooth module

- 2 RGB LED

-3 Resistor 250 ohm

- Cable Arduino

- Lap top to make programming of the Arduino and also to make the application

- Mobile to use the App

- Wires

-Plastic

You will get plastic not very dark to can show the light

And you will design as you like cube or rectangle or a Cylindrical as I made I made it in a quite small Cylindrical

you will connect the LED and the Bluetooth meduol as show in the photo Bluetooth meduol

Tx……………………….Pin 1

Rx…………………….....Pin 0

RGB LED

Green in Pin 11

Red in Pin 10

Blue in Pin 12

I used thunkable Website to make the app

http://app.thunkable.com

coz its very easy to make a app in this website and its like AppInvator In the app when you click in the buttons its just send a data by using the Bluetooth communication

The Arduino receive data from the mobile by using the app via the Bluetooth

Like when receive a 2 make a Blue light

And when receive

7 else if (data == '7')

// Purple (turn red and blue on):

{ digitalWrite(10, HIGH);

digitalWrite(11, LOW);

digitalWrite(12, HIGH); }

Red and blue will turn on so will make a purple light

Code

#include 

SoftwareSerial mySerial(0, 1); // RX, TX

void setup()
{

  Serial.begin(9600);

  pinMode(10, OUTPUT);  //Red

  pinMode(11, OUTPUT);  //Grean
  pinMode(12, OUTPUT);  //Blue
}

char data = 0;
void loop()
{
  if (Serial.available() > 0)
  {
    data = Serial.read();
    delay(100);
    Serial.print(data);
    Serial.print("\n");

  }

  if (data == '1')

    // Red (turn just the red LED on):
  {
    digitalWrite(10, HIGH);
    digitalWrite(11, LOW);
    digitalWrite(12, LOW);

  }

  else if (data == '2')

    // Blue (turn just the blue LED on):
  {
    digitalWrite(10, LOW);
    digitalWrite(11, LOW);
    digitalWrite(12, HIGH);

  }

  else if (data == '3')
    // Green (turn just the green LED on):
  {
    digitalWrite(10, LOW);
    digitalWrite(11, HIGH);
    digitalWrite(12, LOW);

  }
  else if (data == '4')
    // Yellow (turn red and green on):
  {
    digitalWrite(10, HIGH);
    digitalWrite(11, HIGH);
    digitalWrite(12, LOW);

  }
  else if (data == '5')
    // White (turn all the LEDs on):
  {
    digitalWrite(10, HIGH);
    digitalWrite(11, HIGH);
    digitalWrite(12, HIGH);
  }
  else if (data == '6')
    // Cyan (turn green and blue on):
  {
    digitalWrite(10, LOW);
    digitalWrite(11, HIGH);
    digitalWrite(12, HIGH);

  }
  else if (data == '7')

    // Purple (turn red and blue on):
  {
    digitalWrite(10, HIGH);
    digitalWrite(11, LOW);
    digitalWrite(12, HIGH);
  }
  else
  {
    digitalWrite(10, LOW);
    digitalWrite(11, LOW);
    digitalWrite(12, LOW);
  }
}

And in finally you will get a cool light by very cheap bell
