Precision Servo Control

Concept Servo motors are the muscles of robotics. They don't just spin; they hold a specific angle. This project creates a command-line interface to precisely target the servo arm to any angle between 0 and 180 degrees, demonstrating feedback control systems.

The Tech Stack

• Hardware: SG90 Micro Servo.
• Logic: Pulse Width Modulation (PWM), Signal Parsing.
• Libraries: Servo.
• Objective: Interactive angular control via serial input.

How it Works The Arduino generates a specific PWM signal where the width of the pulse determines the angle of the shaft.

1. Parsing: The code reads strings from the console ("MIN", "MAX", or "45").
2. Validation: It converts text to integers and applies safety limits (clamping values between 0-180) to prevent mechanical damage to the gears.
3. Actuation: The servo.write() function translates the angle into the correct microsecond pulse width sent to the motor.

AI Context 🤖 AI generated the robust input parsing logic, allowing the system to handle both keywords ("MIN") and raw numbers interchangeably, and added the safety bounds to protect the hardware.

Status ✅ Operational | Servo responds accurately to angular commands.
