Story

This project is "Comuter communicate with cell phone by using arduino"

Download the application "Bluetooth spp pro".

Nest, connect your phone and blutooth module.

Then you can chet computer with phone like these.

You can use this technology in real life.

By chetting, you'll be able to turn the light in your room on and off likely following pictures' LED

// How to rename a Bluetooth module
// Enter "AT" on serial monitor and click transfer button. "OK" is displayed on serial monitor if it works normally.
  // Enter new name of Bluetooth module "AT + NAME'New Name ', if OK," OK "is displayed on the serial monitor.
  // If the new name is gledel, write "AT + NAMEgledel"
