thank you very much for the reply, I have relays to control the motors but am currently working on a simple h-bridge.
I have the following electronics and mount:
ARduino Duemilanove ATMEGA328P
ARduino Mega ATMEGA1280
Real Time Clock Module - RTC DS1307
Compass Module Arduino - HMC6352
ARduino LCD Keypad Shield
Linear Actuator with reed-switch---------Altitude
Worm Gear Box Motor with reed-switch---------Azimuth
Alt-Az Mount http://s14.directupload.net/file/d/2885/meqygf3a_jpg.htm
I think is a very good idea if you create your sort of Solar App Store for your Arduino SolarMega board platform because for example I try to be friendly to the environment and it seems more convenient if you sell the software instead of hardware (heavy to send), unfortunately I can´t coding and i agree with the open spirit of the Arduino platform.
I appreciate any help in advance, ( excuse my english!!! smiley-red)
