Sweeps the shaft of a RC servo motor back and forth across 180 degrees.

EXPANDED TECHNICAL DETAILS

Geometric Motion Foundations

This fundamental robotics project demonstrates the precise control of angular movement using Pulse Width Modulation (PWM).

  • Sweep Timing Algorithm: The Arduino iterates through a 180-degree range in 1-degree steps. On every step, the firmware sends a specific pulse width (typically $500\mu s - 2400\mu s$) to the servo motor, ensuring smooth and controlled rotation.
  • Temporal Loop Control: Uses the delay() or millis() function to set the "Scan Speed." By adjusting the delay between degrees, the user can create high-speed movements or slow, cinematic sweeps.

Hardware Hub

  • Signal-to-Torque Linkage: Explained the necessity of a shared ground between the Arduino and the servo power supply to prevent erratic "Jittering" during the sweep cycle.
