for controlling led strip lights in our bedroom, I'd like to use an arduino with 2 rotating knobs. They should be incremental; e.g. giving some 2-channel pulses depending on rotating direction. One at the bed, the other at the door.
In the dark in the night, a touch screen does not appeal to me. I rather have a physical knob you can feel and then gently turn for dark -> increasing brightness.
Maybe a stupid question, but does anyone have a suggestion where to find such knobs? I do know the potentiometer / rotary encoder units with a 5-6 mm shaft and a knob to attach on it, but I'd like a more robust and integrated unit. I don't wat to make an enclosure and be afraid the kids will break the thin shaft.
I do like this one: https://www.waveshare.com/esp32-s3-knob-touch-lcd-1.8.htm
though it includes a display as well (which I don't really need, or maybe for an alarm clock?) and I don't know how to easily attach this to the arduino. I rather have 2 I/Os coming in the arduino that I can program my sketch around. ESPs with their own firmware never worked for me :(
My suggestion is to use the rotary encoder, it will probably be the best survivor, there is no rotation stop and getting integer values is simple coding. Sample at the edge of one of the outputs, the other will give you direction. If it goes wrong reverse the two connections.
