I am a complete newbie and I’d like to build a very simple robot. I have an engineer in the wings to help me out if I get lost.
My idea is fairly simple
-chassis of wheels https://www.sparkfun.com/products/10825 $14
-aurdwino? Not sure but the cheaper the better could I use https://www.sparkfun.com/products/11114 and if so do I need a separate battery? $9, but $20 if I need a battery
-Photo sensor https://www.sparkfun.com/products/9088 $2
I want to make the robot go straight forward if the photo sensor sees light, preferably a laser light pen.
Could this be done and if so how much would it cost?
