4 bit adder. Took me a few evenings this week to put together. Im quite happy that it worked first try without any bugs. Constructive criticism is encouraged.
Thanks. Keeping the wireing neat allowed me to walk away and pick it up again without losing what i was doing. It also helped me get it so the first time I powered the circuit it worked as intended.
Going to ponder my next project. I want to make a counting circuit. Basically just a bank of adders on a clock signal putting the output into memory then feeing that number back into the bank and add 1.
