Arduinik is my new toy! I am going to bring him to school I have been working on him for two months! He is my dream come true for the most part! He has a QTI sensor which I configured so it can sense light. When it is dark, the light on Pin 13 will turn on, but I have it programmed to turn on a light strip on pin five too if you install one! Arduinik is one great robot. He can maneuver objects. If he sees an object within 10 cm then he halts turns his head and turns the way that there is no object. He first his head left if there is no object within 10 cm then that is where he goes. if not then he goes right. Even if he goes right a lot instead of re-calibrating and mess if he is in a maze he just turns around eventually! He uses two nine volt batteries to fuel his fire! But in my pictures I have him connected via usb because I was just done with him and I needed to make sure all of his serial comments were acurrate(because that was how I knew he was working right). Make sure to vote for me in the toy and microcontroller contests! :) Look at some of my other projects at http://www.instructables.com/id/Candy-Drop-dispenser/
