Overview

Engineered the control electronics and firmware for an electric fan featuring speed control, oscillation, LED indicators, and infrared (IR) remote operation. Developed the firmware using a PIC16F887 microcontroller with TRIAC-based motor control for efficient and reliable performance.

Key Contributions

  • Speed and Oscillation Control — Seamless switching between multiple fan speeds and oscillation modes.
  • IR Remote Functionality — Enabled full remote operation using standard infrared protocols.
  • LED Status Indicators — Provided clear visual feedback for mode and speed selection.
  • TRIAC-Based Power Control — Implemented smooth, hardware-efficient motor speed regulation.

Outcome

Delivered a cost-effective, user-friendly consumer product with enhanced usability and functional elegance.
