NAND Gate from Scratch (How-To, Using Transistors)

NOT Gates Video:    • NOT Gate with Transistors - Will I blow so...  

Let's build a NAND gate from scratch using transistors.

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/collecti...
