عملية الجمع الرقمية - Full Adder 4008 (4Bit)

Arduino + LCD demonstrating the 4008 IC Full Adder !
The 2 red DIP Switches are the 2x4 bit inputs and the 5 LEDs are 4 bit output + one LED for the Carry out bit!

And here is some information about Adders and full Adders (Wiki):
In electronics, an adder or summer is a digital circuit that performs addition of numbers. In many computers and other kinds of processors, adders are used not only in thearithmetic logic unit(s), but also in other parts of the processor, where they are used to calculate addresses, table indices, and similar.


  1. Hi,

    I have see your full adder arduino project. It's possible to have the code of Arduino's sketch. I want to test full adder on my pc. Thanks it is important for me because I have to do a University project.

    my mail:

  2. Hello, As you see in the video, the Full adder is based on the 4008 ic and the Arduino is used only to display the results. Unfortunately i dont have that code any more, but the code is just to display the adder output.
    Good luck
