This circuit is a complete binary adder! Using at least 7 half adders, you can make a full adders.Button 1 is 8, button 2 is 4, button 3 is 2, button 4 is 1, button 5 is 8, button 6 is 4, button 7 is 2, button 8 is 1. You might need to do some decoding with the letter output. Please tell me how to decode the letters in the comment section.
