When a person passes nearer to it then it sends msg to the user's mobile and asks to enter the password if the user puts the correct password then the

led will on.

you have to install one app call Arduino Bluetooth from playstore. And in this app, you will get the message.

EXPANDED TECHNICAL DETAILS

Remote Spectral Illumination

This project creates a wirelessly controlled LED lighting fixture that can be adjusted for brightness and color from a smartphone.

  • Serial Character Mapping: Communicates via an HC-05 or HC-06 module. The Arduino listens for single-character serial commands (e.g., 'A' for Bright, 'Z' for Dim) and translates them into high-frequency PWM duty cycles for the LED.
  • Multipoint RGB Mixing: (Advanced version) The Arduino receives 24-bit HEX codes from a mobile app. It then independently adjusts the R, G, and B LED channels to produce any of 16 million custom colors wirelessly.

Efficiency

  • State Persistence Logic: Saves the last selected color to the Arduino's EEPROM; when powered back on, the smart LED instantly returns to the user's previous lighting state.
