The Advanced User Controlled Roof Top Antenna Signal Tracking System with Geared DC Motor is designed to improve television and wireless signal reception by automatically aligning a rooftop antenna toward the strongest signal source. The system uses a PIC microcontroller as the main control unit and employs IR transmitter and IR receiver modules for signal detection and tracking. Based on the received signal strength, the microcontroller controls a geared DC motor through a motor driver circuit to rotate the antenna in the desired direction for optimal signal reception. The system also incorporates an LCD display to provide real-time status information, LED indicators for operational monitoring. A regulated power supply ensures stable operation of all components. This project reduces the need for manual antenna adjustment, improves signal quality, and provides a reliable, user-friendly solution for rooftop antenna positioning and tracking applications.
