I had spare time, so I made this.

EXPANDED TECHNICAL DETAILS

Wireless Navigation via Light

This project uses Infrared (IR) signals to create a low-latency, short-range remote control system for a mobile robot.

  • IR Protocol Decoding: Uses a 38kHz IR receiver. The Arduino decodes the specific 32-bit hex strings sent by a standard TV remote (e.g., a Sony or NEC remote) and maps them to "Forward," "Backward," "Left," and "Right" maneuvers.
  • Dual H-Bridge Control: The Arduino manages a L298N driver to control two DC motors. It uses PWM signals to enable smooth acceleration and gradual turns.

Responsive Maneuvers

  • Hold-to-Move Logic: The car only moves while the button is held. The firmware uses the "Repeat Code" feature of the NEC protocol to detect if the user is still pressing the button, ensuring precise control in tight spaces.
