Improve the OLED VU meter with a little bit of physics

Last month, we launched a project to recreate the iconic mechanical VU meter using Arduino and ordinary OLED displays. It is cheap and easy to implement, and promises to bring a little retro style to your originally completely modern project.

[sjm4306] I like this idea, but think it’s a bit too stiff. So he has been trying to add some physical to the virtual pointer of the meter A better approximation of unique hysteresis and overshoot, which is an important part of analog indicators. Obviously, this is something that can only be appreciated in sports, so please check out the video below to get a closer look at his quasi-retro indicator.

Unfortunately, there is currently no code for you to use, but [sjm4306] Said that he will post it on the Hackaday.IO page of the project after cleaning it up. We know that prying a real analog indicator from some hacker’s toolbox requires more than just a few wiggly pixels, but anything that helps to improve the digital approximation of this old hardware is a win in our book. .
