Hey Arduino forum, I have a question that maybe you can answer. I have been involved in some basic around the house hacks, and light animations with Arduino but nothing like this. I want to take my old JukeBox and program the Keys "A-K" and "0-9" to pick a song and play it as if it was a functioning Jukebox, just digital. Its 20 inputs I need to know How would I go about programming them with momentary switches? And how would I go about having it automatically selecting the desired song, playing it, and returning to a 'stand-by' state awaiting its next selection. Also maybe you can select 5 songs to be added to a que as well. Please let me know how to go about this. Or even where to start. I am very eager to being this big project.
This seems to me more like a jukebox forum topic than an Arduino topic.

Tell us how the keys actually work. are they individual, independent switches? Are they SPST switches?
Do the digit switches and the letter switches have to be pressed at the same time, or is there any linkage between the switches?
Does the operator always have to press both switches?
If switches are independent SPST, then look at the Arduino sample program for keypads that use a ladder network and an A/D pin to measure the voltage produced when a key is pressed.

The Switches currently are independently controlled mechanical switches. However they could be swapped out for just simple momentary switches. and currently a letter which stayed pressed down mechanically while you select a number. Once a number is selected it we depress the button automatically. However I don't care whether or not the button stays pressed during the digital build. And yes the operator presses both switches.

Again, your question is more about mechanics and jukebox-specific items, rather than Arduino-specific.
Find some documentation or do your own homework on how these switches work.
