“The following Instructible deals with making a simple line following robot using arduino uno. Please note that I am a beginner. This is my first time working with arduino. I welcome all criticism, comments and advice. :) This project, I believe can give you a good intro into using arduino micro controller. For a pro, I do not think it will take more than 2 hours, but for a noob like me, it can take a week, learning each aspects one by one.”
