Solar Cell Tracking

Beschreibung

Experimental Solar Cell Tracking Project for under $10 Recently purchase a couple of the small Solar Cell Modules on eBay (80x104mm 5V 250mA) and they work fine but it's time to add some tracking... The 3D printed parts are simple enough so I thought I'd share... I haven't written the code yet but will probably use one of the Arduino modules as I have lots (code has been added)... Just to note I don't use LDR's to track the sun, I simply measure the solar cell's voltage and move it left/right, up/down a few degrees and determine the best position, no rocket science here, just simple measurements (will publish code when finished)... Electronics Enclosure Test enclosure allows for one or two PCBs and up to two 18650 batteries. The top is secured with four screws and cut-outs are included for the Solar Cell cable, horizontal servo cables and circular on/off button, the wall thickness is 3mm. I may add a more compact version later...
