I am new to electronics and this is my first project. I want to make a 6 or 8 bit adder in which the 2 numbers being added have a 7 segment display, and the final output is displayed on a display. I want to use adder chips (7483). Can I just connect 2 4 bit adders to get an 8 bit adder? if so how? Also, can I connect 2 display drivers to get 2 digits? How would I display an 8 bit binary number on a 7 segment display(s)?

Sorry if this is a lot of questions :) Im a newbie.

Thanks,
William

OK, a number of issues. 8 bits is 0 to 255 (three displays) or 00 to FF (2 displays).

The output is 0 - 510 (three displays) or 0 to 1FD (three displays).

It would be far easier to display the input and output as hex (00 to FF) than decimal (0 to 255).

Check the datasheet for the adders. It is quite likely that they will tell you how to create an 8 bit adder.
