The Tiniest Keyboard

Hello, I&#39;m Newtle Kim.This time, we designed and manufactured a keyboard PCB ourselves to make a mechanical keyboard that is really close to a product.But the fact that it&#39;s keyboard for one Key.I prepared the series content because I thought that if I increase the key step by step from the 1Key, no matter how much DIY beginners can make it. :) I also attached &#34;3D Model File&#34; + &#34;Arduino Source Code&#34; + &#34;PCB Production File&#34; below.- Production video link: - Arduino Source Code (for shots) Link: https://drive.google.com/file/d/1TWF0...- PCB Fabrication File Link: (1) Gerber files : https://drive.google.com/file/d/1eLup...<span style="background-color: rgba(0,0,0,0.05); color: rgb(19,19,19); font-size:
