Quick Videos: A Full Adder

The complete circuit diagram can be downloaded from here: adder.pdf

All of the parts are the same as the ones used from the first Quick Video. To recap, they are:

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.

If you wish to build this as a 1 bit adder that can be chained with other adders, build just the adder as shown in the circuit diagram; the LED driver circuits can be omitted until it’s time to present the results.
