For Digital Electronics Subject, we had taken Half adder. Basic design and construction of project was explained by our DE faculty Mr.R.Yasodharan, AP/MCT. Then we started to analyse about component working and its implementation, after we starting hiccups we implemented Half adder in bread board. Following are the description of it.
The half adder adds two single binary digits A and B. It has two outputs, sum (S) and carry (C). The
carry signal represents an overflow into the next digit of a multi-digit addition.
The value of the sum is 2C + S. The simplest half-adder design, pictured on the right, incorporates an XOR gate for S and an AND gate for C. The Boolean logic for the sum (in this case S) will be A′B + AB′ whereas for the carry (C) will be AB. With the addition of an OR gate to combine their carry outputs, two half adders can be combined to make a full adder.[1] The half adder adds two input bits and generates a carry and sum, which are the two outputs of a half adder. The input variables of a half adder are called the augend and addend bits. The output variables are the sum and carry

nice to see the project working
