🚀 Rocket Gimbal System

This project is a Bluetooth-controlled thrust-vectoring gimbal system designed for a model rocket. It uses two servos for pitch and yaw control, an ESC-controlled brushless motor for thrust, and a fully custom 3D-printed baseplate to mount and protect the internal components.

✅ Designed and built from scratch for hands-on control and embedded systems practice.

🎯 Features

• 🎮 Real-time control via Bluetooth joystick (HC-05)
• 🧠 Smoothing + dead zone logic for stable servo movement
• 🛞 Thrust control via ESC with remapped microsecond ranges
• 🚨 Manual override switch for safety
• 🧩 Modular 3D-printed design for each mechanical part

🛠️ Build Notes

• All parts are designed to fit inside a 3D-printed cone-style baseplate

• STL dimensions optimized for M3 hardware and RS2205 prop clearance

• Cone diameter: 200mm | Height: 82mm | Rocket body: 84mm diameter

• Getting Started

1. Open Code_for_Rocket.ino in the Arduino IDE.
2. Make sure you have these libraries installed:
   • Servo
   • SoftwareSerial
3. Upload the sketch to an Arduino Uno.
4. Connect the circuit according to the wiring schematic.
5. Send Bluetooth commands from your joystick app.
