Just plumbing the depths here, before I start to try and wrap my head around how to do it. I’ve got two Arduino Shields, and am planning on following the tutorial for the expression pedal conversion with at least one of them. I am not super familiar with that architecture, so forgive me if this sounds like a silly question, but I’m just going to phrase it this way, 'cause that’s how I understand it.
Is it possible to use one Arduino Shield for multiple functions? Perhaps have a Shield with one or two buttons and also an expression pedal input? Is it just something to change in the coding part of it? 'Cause it seems like there’s a lot of options to solder or pin things to, and I’m just curious if I could have that much more functionality out of one device. Especially when working with the premium of space on my pedalboard.
