As far as input equipment go, the potentiometer is fairly clear-cut: flip it remaining, switch it suitable, and you’ve fairly a great deal seen all there is to see. For many purposes that’s all you require, but we can unquestionably strengthen on the expertise with contemporary engineering. Enter this promising job from [upir] that pairs a prevalent potentiometer with a cheap OLED screen to make for a significantly a lot more partaking consumer experience.
The primary idea is to mount the exhibit around the potentiometer knob so you can demonstrate valuable data these types of a label that shows what it does, and a readout of the at the moment detected benefit. But you are going to probably want to present the place the knob is presently set in the assortment of possible values as well, and that’s in which factors get appealing.
In the video clip immediately after the crack, [upir] spends a substantial amount of time explaining the math guiding information like the scrolling tick marks. The almost 45 minute extended video clip wraps up with some optimization, as having the display to transfer together with the knob in genuine-time on an Arduino UNO took a bit of further effort and hard work. The ultimate outcome seems terrific, and guarantees to be a comparatively low cost way to increase an sophisticated and useful little bit of flair to an if not essential knob.
With the code and this substantial demonstration of how it all is effective, including a similar ability to your up coming knob-outfitted gadget shouldn’t be way too significantly of a problem. Perhaps it could even be combined with the OLED VU meters we have included earlier. Be positive to allow us know if you close up using this system, as we’d enjoy to see it in motion.
Thanks to [Marko] for the tip.
