I am working on a project that is for right now going to be a couple of footswitches and an arduino to use as a MIDI controller for a program i use. I would like to somewhat “future proof” my design as in the future I will likely want to be able to plug in an expression pedal with a 1/4" TRS input jack and was having some difficulty sifting through information as to what exactly I would need.
Do I simply just need a TRS input jack? A TRS jack with a pot that matches the resistance of the pedal? Etc?
Thanks for any advice you might have
