Hi, i'm making something like a pinball machine for my tech class and i wanted a way to show the score digitally like on a led digit display. I searched google for something like it but i couldn't find anything. I was thinking of ripping out the electronics from another pinball machine and putting that into my own but it cost's more than my budget. I need something that when the metal ball hits the contacts it would result in points that would show up on the led's. and i want the points to add up just like a normal pinball machine. I know little about electronics and any help on this would be greatly appreciated.
