Dual Axis Solar Tracker

thingiverse

This project demonstrates a simplified dual-axis solar tracker, where the servo motor weight doesn't strain the system. The pitch gear is housed within the bracket to reduce wobbling and enhance professionalism. The horizontal gear system attaches directly to the panel mount for a robust structure. This is the creator's first attempt; they request pictures after construction. Two video links are provided, and a similar project with no printed parts is mentioned as well. Requirements include an Arduino Uno, two SG90 Micro servo motors, four light-dependent resistors (LDRs), a breadboard, wires, rainbow ribbon cable for LDRs, and a 4" long 1/4" bolt and nut. Assemble the parts in order: attach the horizontal servo motor to the tracker base before adding the horizontal gear; mount the gears to the servo motors using brass nails and a soldering iron; connect the motors, gears, and panel mount; hook up the wires according to the schematic; load the program into the Arduino and test it out. Adjust resistor sizes on the breadboard as needed based on the light used for movement.
