Solar Tracker

I am new with arduino Atmega328p and i am doing a project on dual axis automatic solar tracker using LDR sensors. Anyone can please help me for the project.

Please don't multi-post.

with the usage of 2 LDR

Another way to make it try all positions and measure voltage and then move back to the best position.

Actually while searching for first 1 found this 1, nice stuff

I think first video is preaty much self explenatory, except in ur case u need 4 LDR and 2 servos(that is, if u dont have 2 big solar panels or should i rather say to heawy)
