Building a 4-Bit Adder using Logic Gates

[@1993scroton]

i would like to ask u something. in the 8th minute you added 1+1=1 and carry 1 , however it should be 0 carry 1, am i wrong?

[@ubaidurrehman4377]

Good, but swap the last two bulbs because the second last bulb represents carry out while the last bulb represent the 4th digit.

Hi thanks for the tutorial. I have a question. if I add 0111 + 1000 (7 + 8 in decimal) I get 1111 in binary now if I connect it to a seven segment display of-course it will shows an "E" as a result. I wanted it to be 0001 0101 (1 & 5 in decimal) so that I can put it in two digit seven segment display. How am I going to do that? Thanks in advance
