Dual Axis Solar Tracker
Attach horizontal servo motor to tracker base before attaching the horizontal gear or you will have trouble with tool access to get the motor mounted. The vertical servo gear should be ok to assemble first due to the smaller size. To mount the gears to the servo motors, I cut tiny brass nails just a bit smaller than the thickness of the gears and made little groves on the nail to give a rough surface for the plastic to bond to. I then used a soldering iron to heat the nail and fuse it through the white servo gear attachment and then into the plastic gear. Makes for a nice, clean installation. Just make sure that your gear is exactly centered when you mount it to the servo.
Attach motors, gears, and panel mount.
Hook up wires according to schematic.
Load program into Arduino and test it out.
Depending on the light that you use to move your tracker around, you might need to change the resistor size on breadboard (they should all be equal value, higher value resistors for less light).
