Blutooth Switch (Arduino)

 BLUTOOTH SWITCH (ARDUINO)

Hi, Using this we can control leds using Smart Phone via Blutooth. We can also control home appliances using Relay with it. For Video : CLICK HERE .

THING'S NEEDED

1. Arduino UNO R3.
2. HC - 05 Blutooth Module.
3. Leds or Relay (For 240v).
4. Breadboard.
5. Jumper Wires.
6. 9V Battery
   

CIRCUIT DIAGRAM

WIRING

ARDUINO TO BLUTOOTH MODULE

• Connet the VCC of Blutooth Module to 5 + of Arduino.
• Connect the GND of Blutooth Module to GND od Arduino.
• Connect TX of Blutooth Module to RX  of Arduino.
• Connect RX of Bultooth Module to TX of Rduino.

NOTE : REMOVE THE TX & RX CONNECTION OF BLUTOOTH MODULE BEFORE UPLOADING THE CODE (THE CODE WILL NOT BE UPLOADED IF DID REMOVED)

ARDUINO TO LEDS

• Led 1 - Pin 13 of Arduino.
• Led 2 - Pin 12 of Arduino.
• Led 3 - Pin 11 of Arduino.
• Led 4 - Pin 10 of Arduino.
