Bluetooth Servo Control System
Budget: €18 – €36 EUR
I need a compact Bluetooth-enabled regulator that can reliably drive standard hobby servo motors. The core task is to design and program a small board (Arduino, ESP32, or a similarly common MCU) that pairs with a mobile or desktop app and sends position commands over Bluetooth.
Board max 7mm x 35mm
Essential requirements
• Drive one or more standard servo motors with smooth, jitter-free motion.
• Bluetooth link must let me choose from several pre-set positions or motion sequences that you define in firmware and expose in the UI.
• Clean, well-commented code and a brief wiring diagram so I can reproduce the setup.
Nice to have (not mandatory, but let me know if you can add them easily): adjustable speed curves, basic calibration routine, and OTA updates for future tweaks.
Deliverables
1. Circuit schematic + parts list.
2. Firmware source compiled and flashed to a test board.
3. Simple cross-platform control interface (mobile app, desktop tool, or web Bluetooth page) showing the pre-set options and connection status.
4. Short read-me or video clip proving the system moves a standard servo through the defined presets.
I already have servos on hand for testing, so once you send the build guide and code, I will replicate your setup and confirm operation. Looking to start immediately and iterate quickly—please outline your proposed tech stack and estimated timeline when you reply.
