Sun lovi'n solar panel

Update: Code added as an *.ino file
---------------------------------
My first moving thing. I'ts still ongoing. I created it as an experiment to see how effecient i could make it. The plan beeing is to make it self sufficient. So far i have failed to locate a rechargeable powersource around 5 volts that is small enough to make this a challenge.

It's an easy build containing:
2x 9g servos
1x Arduino Nano
4x 91 Ohm resistors
1x solarpanel
1x Soldering lab board
4x Light sensitive resistors
some cables
Glue gun

All the pieces are easy to find online. If you need the code (fairly basic so far) it's in the files section. I included the CATparts if you want to scale this to fit other solarpanels and/or lab boards. It will probably work in any scale. Using steppers probably works just as good if you change the code an build a stepper driver..
