The Arduino Bluetooth Controller by ROBOBOY is a versatile app designed for controlling Arduino and ESP Bluetooth projects remotely. It offers four control methods: buttons, rotation sensor, voice commands, and Serial Monitor. Users can save and manage their projects with custom names, edit them, and delete as needed.

The app provides 22 command buttons for various actions, 16 commands based on phone rotation for precise control, 9 voice commands using Google speech services, and a Serial Monitor for text-based communication with Arduino or ESP projects. Additionally, a built-in terminal allows users to send commands to Bluetooth modules and view responses on the communication screen.
