Quick Videos: Gates

As promised, the PDF for the five separate circuits implementing our five gates: AND, OR, NOT, NAND and NOR: Logic Gates.pdf

In addition I ordered the following parts for the circuit:

You will also need wire; I used the 22AWG Solid Hook Up Wire Kit, and all this goes a lot faster if you have a wire cutter and a wire stripper. And of course you’ll need a breadboard to hook everything up with.

For power I simply used a battery pack and a couple of AA batteries.

(Addendum: the circuits that are used in this Quick Video are not useful if you’re building larger circuits. Specifically the AND and OR gates can’t really be used in complex circuits; see the revised Introduction to Digital Computers (part 1) video for more information.)
