Do you mean you want to learn how to program the $50 robot? If so Google "C tutorial", and/or look at the code that Admin has already written.

To do that you need something called an H-Bridge, you can either make your own: http://www.societyofrobots.com/schematics_h-bridgedes.shtml (http://www.societyofrobots.com/schematics_h-bridgedes.shtml) or you can just buy a chip that will do pretty much the same thing, like this: http://www.sparkfun.com/commerce/product_info.php?products_id=315 (http://www.sparkfun.com/commerce/product_info.php?products_id=315) (there are other chips you can buy). To decide which H-bridge to buy (or make) you first need to know how much current your motor will draw.

Hi,

It's Saturday and it's my duty to kill those bottles of scotch, so my spelling robot got too much "oil" it seems - or was it my keyboard ;D
