📦 Installation

1. Wiring

   • Connect the HC-06 module to the Arduino as follows:
     • HC-06 TX → Arduino Pin 10 (RX)
     • HC-06 RX → Arduino Pin 9 (TX)
     • HC-06 VCC → Arduino 5V
     • HC-06 GND → Arduino GND
   • Connect the LED to Pin 13 of the Arduino and the other leg to GND.

2. Upload the Code

   • Upload the provided Arduino code to your board using the Arduino IDE.

3. Bluetooth Pairing

   • Pair your mobile device with the HC-06 Bluetooth module using the default password "1234".

4. Mobile App

   • To interact with the Arduino via Bluetooth, you can use the following mobile app: Download Bluetooth Serial Monitor on Google Play
