Let me introduce you to Carbopad.

Carbopad is a macro pad I created using whatever materials I had on hand. I chose the name because the only material I could use for the case was cardboard since I don’t own a 3D printer and I wanted to give it some personality. Carbopad is one of my first projects, and I’m very proud of it. I think it’s time to stop talking about how I got this idea and move on to describing how it works.

Carbopad has 4 buttons. One for copying text and another for pasting. The other two serve as Ctrl+Z and Ctrl+Y. The main use I’ve found for it is when programming other projects. The microcontroller I chose for it is the ESP32. In my Flavortown devlogs, you can also see how it’s built from the inside. I hope you like the Carbopad as much as I do :)

To get the buttons to work via Bluetooth, I used: https://github.com/T-vK/ESP32-BLE-Keyboard
