Hey, so for an upcoming project, I'm looking at getting an Arduino Uno and basically building my own MIDI controller (original, I know), with a reflashed USB chip so it shows up as a MIDI in device to any PC it's plugged into.
I'm not entirly sure what I'll be building into it yet, but basically a bunch of various pots, maybe a few encoder wheels + buttons. With an I2C bus and port expander chips to make it all run.
I've started to look for linear Potentiometers on digikey but it presents me with a bunch of different option, "Top" "side", etc, so I'm looking for advice on what to get.
Cheaper would be nicer, my budget for this project is somewhere around $100, but I'd like for the Pots to be fairly loose and smooth, I have little experience with them so I'm looking for osmeone with insight to maybe explain and suggest.
If you like cheap and not afraid to solder an electronic scrapheap could be very interesting.
That said, first try to define what you want to make, if you don't know you probably will buy things not needed (directly) and that is/feels similar to a budget cut.
Have you checked the yourduino site? It is in China and the owner is a frequent visitor of this forum. e.g.
All electronics show about a dozen slide pots in their 3 pages of pots, most around $1 each. You do need to first determine the type of pot response you require, audio taper or linear taper, and the total resistance range you require for you design.
