🤖 Robot Arm Control using Arduino Uno

This project demonstrates how to control a 4-degree-of-freedom robot arm using Arduino Uno and four potentiometers. Each potentiometer adjusts one servo motor.

---

🧠 How It Works

• Potentiometers send analog values to the Arduino.
• Arduino maps those values to servo angles (0°–180°).
• Servos move the robot arm accordingly.

Non-obvious tech & libraries

• Arduino Servo library – bundled with the IDE but often overlooked for multi-axis work.
• TinkerCAD Circuits schematic (circuit_diagram.png) – handy cloud simulator for quick validation.
• USB CDC serial monitor – quick-and-dirty telemetry without extra hardware.
