I've seen a lot of posts on here about how people have created their own sim pits and panels. It has inspired me to the point of wanting to create a simple switch panel of my own. I haven't done much with electronics for over a decade, and wanted to get some advice on USB microcontrollers/control boards. This has sparked a couple of questions that I'm not 100% certain on, and I would appreciate any advice.
What I'm looking at doing is a small footprint box containing toggle switches, buttons, and maybe some rotary encoders (with push buttons of course). It will be 16 electrical components, broken down as follows:
4x ON-OFF-ON switches
4x ON-OFF switches
4x MON-OFF switches
2x ON-OFF-MON switches
2x Rotary Encoders w/ MON-OFF Push Button
If I'm thinking correctly, this would be 32 inputs. The question I have is: What microcontrollers should I be looking at? Arduino, Teensy, ye-ol'-Chineese-knockoff? Also, how many inputs can I get away with on one of those boards if I consider something like a shift register or matrix?
