Hi
I want to use a stepper motor for rotating the solar panel such that the panel faces the sun. I will be using PIC or any other avilable options. Any help with codes driving circuits will be helpful
Many Thanks

Can you get hands on PICAXE-18 (PIC with BASIC interpreter)?
Here is an example of BASIC code ..

Also, as this microcontoller has build-in ADC you can use it to "read" a light sensor to "follow" the Sun ..
Regards,
IanP

| How much current do you need in driving the stepper motor? Also note the voltage. It's better if you will use a stepper motor driver circuit because it offer more flexibility. You only need to input the direction and clock pulse for every step.

| Suggest that there are quite few application notes on this subject from www.microchip.com

| Any driver IC like ULN2003 will suffice ur purpose. You can easily drive universal stepper motor with such driver IC's. You dont need a special driving circuit as such.

Are you developing a sun tracker(solar beamer) in which solar panel is always perpendicular to sun to get max. radiation. I have done this earlier
see mine
http://geocities.com/njbibin/robotics/suntracker.html
I have given explanation how to make it more efficient in robo.pdf . You can download it from files section of yahoo group-booksbybibin
