I made a project where I control a servo motor with a TV remote control.

If you press "0" you set the servo at minimum angle. If you press "3" you set the maximum angle.

If you press "1" or "2" you set the servo +10 or -10 degrees, and print LCD angle value.

EXPANDED TECHNICAL DETAILS

IR-Based Wireless Motion

This project bridges the gap between consumer electronics and physical robotics by hijacking the Infrared (IR) signals from a standard TV remote to control high-precision servo motors.

  • Protocol Decoding Logic: Uses the IRremote library to capture 38kHz pulses. The Arduino decodes the specific 32-bit hex strings (e.g., 0xFF30CF) and maps them to incrementally increasing or decreasing servo angles (0-180 degrees).
  • Incremental vs. Absolute Control: The firmware includes two modes: "Step Mode" (press a button to move 5 degrees) and "Memory Mode" (preset positions like 45, 90, 135 degrees), providing a flexible interface for remote-controlled camera gimbals or robotic arms.

Feedback Interface

  • Visual Position Tracker: The current servo angle is updated in real-time on a 16x2 I2C LCD, allowing the operator to verify the motor's position without line-of-sight to the hardware.
