After I attended a beginners course held by Geir Andersen I got inspired to make a little car. So last summer at late hours between my shifts at work I made this at a very low budget. Basically it does three things: 1 - Plays the Axel F melody (also known as the theme song for Crazy Frog) at different speeds. 2 - Check your "finger print" by a thermo sensor at the nose of the car. 3 - Chased by the light when the light dependent resistor at the front and the back are activated.
