Flutter Control Panel

A servo motor control app built with Flutter, featuring multiple communication methods (Wi-Fi, Bluetooth, USB Serial) to control 4 servo motors.

Features

Core Functionality

• Multi-Protocol Communication: Support for Wi-Fi, Bluetooth Low Energy (BLE), and USB Serial connections
• Real-Time Servo Control: Individual control of 4 servo motors with smooth slider interfaces
• Pose Management: Save, load, and delete servo positions for quick access
• Visual Feedback: Real-time angle display and responsive UI elements
• Cross-Platform: Compatible with Android devices

Communication Protocols

• Wi-Fi Control: Network-based control with HTTP API integration
• Bluetooth Control: Direct BLE connection for wireless operation
• USB Serial Control: Wired connection for stable communication

Hardware Integration

• Arduino Support: Complete Arduino sketch for servo control
• ESP32 Integration: Wi-Fi and Bluetooth communication handling
• Backend API: PHP-based server for pose storage and retrieval

Getting Started

Prerequisites

• Flutter SDK (>=3.8.1)
• Android Studio or VS Code with Flutter extensions
• Arduino IDE
• PHP server (for Wi-Fi functionality)
• MySQL database (for pose storage)
