EMBEDDED SYSTEM DESIGN FOR SUN-TRACKING SOLAR PANEL – A CLASS PROJECT TEMPLATE AbstractThis paper presents a class project template in which students design the embedded system softwarefor the controlling a sun-tracking solar panel system using microcontroller PIC-16F887. This is aclass project in the “Introduction to Microcontrollers” course in the undergraduate program of stud-ies in Engineering Technology. The students are given a previously designed solar panel with built-in true sun-alignment mechanism and are required to write program to control it. The control systemis required to align the solar panel to a plane normal to the Sun rays by detecting the actual positionof the Sun in the sky over a span of 180 and 90 degrees in the azimuth and incidence planes. Theprogram should detect the sky condition (clear, dark or cloudy), and override the alignment mecha-nism to send the panel to a home position. The alignment mechanism should have a programmabledelayed response to any misalignment incident. The system design employs C programming for themicrocontroller PIC 16F887 from the Microchip Inc. using either CCS-C or Hi-Tech Compilers.Students work in teams of twos, design their own software and test it on the system. Students areencouraged to add special features of their choice. All teams compete and demonstrate their pro-grams in the final lab class. The paper discusses the pedagogical benefits along with the feedbackfrom students.
