I'm planning to use this to control a self built solar tracker as I'd love to go off-grid. A solar tracker will make best use of the available light which as you know we don't get much of in the uk. I'm also planning to make a parabolic solar water heater which will also track the sun and pre-heat my hot water.I'm gonna be posting how it all goes so other people can do the same, if they want to
I am working on the same project!Last night I put libelium-gps, compass and sun motion code together, it seems to work.If I turn my arduino (by hand), a LED will flash when direction is reaching the sun's position (azimuth) Smiley.Next step is to build the mechanics for the disher and the pv panel......I am looking for simple stepper motors.
Hope I can handle the wind force with such a great dish...
Any more updates to this code will be posted here:http://www.mowcius.co.uk/suntrackercode.htmlMowcius
