BTControl: Arduino ESP32

BTControl is a Bluetooth controller and serial terminal app for Arduino, ESP32, HC-05, HC-06, BLE and other DIY electronics projects. Use your phone to connect to compatible Bluetooth devices and control robots, RC cars, relays, lights and custom hardware from a simple mobile interface. BTControl is designed for makers, students, hobbyists and developers who want an easy way to send commands, test Bluetooth communication and build mobile control panels for their electronics projects. What you can do with BTControl Connect to nearby Bluetooth devices Send and receive serial data Control RC cars, robots and DIY hardware Toggle relays and switches Send custom commands and values Use joystick-style controls for movement projects Monitor incoming messages from your microcontroller Main features Bluetooth device connection Scan and connect to compatible Bluetooth devices such as HC-05, HC-06, ESP32, Arduino-based Bluetooth projects and other serial Bluetooth modules. Serial terminal Send and receive raw Bluetooth serial data. Useful for debugging, testing sensor values, monitoring responses and manually sending custom commands. Joystick controller Use on-screen joystick controls for RC cars, robots and motion-based projects. Suitable for projects that need directional control over Bluetooth. Switch and relay control Control relays, lights and other outputs with simple on/off switches. Useful for home automation, smart device prototypes and custom control panels. Dial pad and command input Send numbers, custom text and command values directly to your connected device. Light and RGB control Control LEDs and RGB lighting projects by sending color values and lighting commands to your microcontroller. Compatible project types BTControl can be used for projects such as: Arduino and ESP32 robotics HC-05 / HC-06 Bluetooth projects RC cars and robot cars Relay and home automation projects LED and RGB lighting control DIY electronics experiments Bluetooth serial communication testing Custom IoT prototype control panels Supported hardware BTControl is suitable for many Bluetooth-enabled DIY boards and modules, including: Arduino boards with Bluetooth modules ESP32 ESP8266 projects with Bluetooth bridge modules HC-05 / HC-06 / HC-08 modules BLE-compatible devices Raspberry Pi Bluetooth projects Other UART Bluetooth devices Why use BTControl Instead of building a separate Android app for every project, BTControl gives you ready-to-use Bluetooth control tools in one app. You can quickly connect your phone to a compatible device, send commands, test communication and control hardware without building a custom mobile UI from scratch. Whether you are learning Bluetooth communication, building a robotics project or creating a smart control system for your electronics, BTControl helps you interact with your hardware directly from your phone. Useful for Arduino learners ESP32 developers robotics hobbyists IoT makers students building mini projects Bluetooth serial debugging and testing Note BTControl works with compatible Bluetooth-enabled hardware and modules. Features available depend on how your Arduino, ESP32 or other microcontroller project is programmed to receive and process commands.
