Share your projects


Four years later I finally started making an OLED screen replacement for the simple and ugly LED bar I made for this project.

Using an Arduino code and a 1.5" RGB OLED display, started working out a crude interface.

Build the general device without too many issues. Wired in 3 buttons to change setting and brightness control. Not some of my best soldering work, but I don't have to look at it once it's in a case.

I found a web utility that makes it easy to create graphics for OLED projects like this, so I mocked up a general idea of how I want it, still work in progress. https://lopaka.app/

I've worked out a bit of the coding, had to figure out how to only trigger screen refreshes only on the change of state of an I/O pin. Figured out Contrast control and such.

I still need to design an enclosure, and a ton more coding and debugging. I'll share more when I'm done...

Tip: If your push buttons sometimes act up, you might need to debounce them in hardware (10k Ohm resistor + 1uF capacitor) or perform the filtering in software by reading a button as pushed if it registers multiple times instead of just once.
