I noticed there are still alot of questions about making a sensor bar or how it works so I made a page with some close up picks of the sensor bar circuit and some explanations. --->Sensor Bar (56k warning- total page size~700KB)
Also if you have any other questions you can post them in this thread.
PS: I know I'm not the first one to do this.
I'll kick your ass at Mortal Combat and Cooking Mama!
