I'm making a pinball machine for my school's yearly musical. This year it's Tommy.I just need to make it look like a pinball machine. its doesn't actually have to function as one. I wanted to know if anyone had suggestions on what kinds of led and lights to use and also for sounds and such. Any help is appreciated, thanks!
You question is difficult, but only because there is such a wide range of options available using an Arduino... all the way up to making a working pinball machine!
I would suggest first determining exactly how you want the pinball machine to look and sound, also if you only want a prop (which will be easier and quicker to interface and program) or an functional pinball machine. Then look at the examples for audio, LEDs, and actuators in their respective sections in the Playground. That should be sufficent to get started, then you can ask more specific questions as they arise.
