Build an AND Gate from Scratch with Transistors

NOT Gates Video: https://youtu.be/yeC9ODMEQvY

Let's build an AND gate from scratch using transistors.

Circuit.js Diagrams from this video are on GitHub: https://github.com/pagekey/education/blob/main/171-AND-Gate/README.md

If you're getting started, I honestly recommend just buying an Arduino kit - they have a little bit of everything in terms of components. I have one from like 10 years ago that I'm still using (at least some of the components in this video are from it). The starter kit is what I used: https://store-usa.arduino.cc/collections/kits/products/arduino-starter-kit-multi-language
