Reply to "Recommendation for a Potentiometer with Stops (Detents)"

Here's a display that attaches to the Arduino with shift registers and uses just 2 output pins. There's the normal power and ground along with a data and clock output.

I used DipTrace to design the PCB and sent the files to JLCPCB for production. It took about 3 weeks to arrive here in Western Pennsylvania. Total cost with shipping was eight dollars for 5 pcbs.

The plan is to mount the display inside an ABS plastic project box along with potentiometers, a push button and 2 toggle switches. Making the cuts in the box may be a challenge. I have brass mounting hardware available for the display.

The display is built sunny-side up with the shift registers all on the bottom.

I wrote an Arduino class called ShiftDisplay that allows me to write just about anything to the two display areas. The test program and class code is included in the attachments. Everything is working according to plan. When I get the box together, I'll have another update.
