Solar Tracker Arduino Project
Overview: This device keeps a flat panel holding a solar cell continuously following the sun as it moves across the sky. The Arduino uses 2 light dependent resistors (LDRs) that are separated by a fin to compare the light levels on either side and then rotate the servo attached to the panel towards the more illuminated LDR until the two detectors are equal. This is a nice Arduino project which combines sensors with servos, with logic that can be tuned, and has a practical application relating to clean energy. Background: Solar panels generate the most electricity when the incoming light is perpendicular to the panel. A...
