Two-Axis Solar Tracking System Control - PIC16F84A
Technical paper describing the development and implementation of an automatic control system for the AureSolar two-axis solar tracking device using a PIC16F84A microcontroller. Covers mechanical design with helical gear reducers and screw-nut actuators for low-power operation, optical sensor design using photodiodes, conditioning circuit, control logic, and power interface. Includes experimental results comparing energy collection performance between the two-axis tracking system and a fixed 45-degree inclined system, demonstrating approximately 50% energy gain.
