Build!
This project was very fin to build, I had a few obstacles with the code and soldering, especially the battery. But in the end I finished and got it to work. Some keys don't fully work, but I really like how this turned out!
Intro
Hello! This is my third blueprint project. After finishing the LED chaser and Hackpad, I wanted something more challenging. So I chose a keyboard. If you want to access my journals, here is the link:
