Arduino Bluetooth Controller 2.8

Arduino Bluetooth Controller is an Android application designed for Arduino enthusiasts looking to remotely control their projects via their Android devices. The app allows users to establish a connection with any Arduino or microcontroller project that incorporates a Bluetooth module. Users have the flexibility to set a UUID for their Bluetooth module to facilitate the connection with the application. An option for using the default UUID for HC-06 Wireless Serial 4 Pin Bluetooth RF Transceiver Module RS232 is also available, with a standard password of '1234' for initial pairing.

The application features four distinct Command Modes:

1. Vehicle Mode: This mode enables users to control a vehicle using specific gestures, utilizing the smart device's built-in accelerometer sensor for gesture interpretation. With options for eight different gestures (FRONT, BACK, LEFT, RIGHT, FRONT_LEFT, FRONT_RIGHT, BACK_LEFT, BACK_RIGHT), users can customize commands via the "Set Commands" menu. The mode also offers buttons for STOP and ANDROID commands, allowing further customization.
2. Fader Mode: Users can experiment with servos, LEDs, motors, and more using a fader-seekbar that sends commands ranging from 0-9.
3. Controller Mode: This mode presents a standard controller layout with ten customizable buttons. Arrow buttons are configured to send continuous commands while pressed, simulating real controller functionality.
4. Terminal Mode: Providing a terminal-like interface, this mode allows users to type and send individual or multiple commands for sequential execution. The application sends each character individually to accommodate Arduino's single-byte reception limit.

All configuration settings and assigned commands are permanently stored within the application and can be adjusted as needed. Additionally, users can modify accelerometer axis orientation and sensitivity settings based on device specifications.

The application simplifies communication between Arduino projects and Android devices while offering a range of control options tailored to different project requirements. It provides versatility and customization possibilities for users engaging in various electronics projects.
