Introduction
Worked on a team to design, build, and implement an Arduino based solar cell array system that could scan and determine the location of maximum light intensity
Responsible for research of theory behind experiment, design and manufacturing (3D print) of 2-axis solar tracking system, assembly and integration of device, and troubleshooting and adapting mechanical and electrical issues
Functionality
The designed system structure, consisting of a circuit casing, solar cell holder, and rotating plate, was built in SolidWorks and 3D printed using PLA. The system has two axis’s of rotation to allow for an optimal searching range. The first rotated the solar cell’s base 180˚ using a DC motor, the second rotated the solar cell 270˚ around its axis using the stepper motor. The system also utilized 10k resistors, a photocell and potentiate.
To test the design accuracy, a phone flashlight was placed different locations 45˚, 90˚, and 135˚ away from each other. The system tracked the light source’s changing location and recorded the final output voltage values within 15˚ accuracy, indicating the system achieved the experiments desired functionality.
