CarboPad

I built a macro pad using an ESP32 and cardboard. I chose cardboard because it was the most readily available material I had—I don’t own a 3D printer. The worst part was when I spent several hours trying to fix the code, only to find out that the whole time the problem was that I had the GND wire in the wrong pin. I learned how to use Bluetooth on the ESP32 and how to organize a project, and also that I need to keep an eye on the pins, haha. Considering this is one of my first functional projects, I’m very proud of it and really enjoyed making it.
