The full adder is a combinational circuit that adds three input bits, rather than two in half adder. You can see the theory in previous page.Our full adder circuit is contents of  three inputs A, B,  and C and two outputs sum and carry.

 Procedure :-

1- Prepare your self before entering the lab by reading about adders and digital design. Then construct your truth table with 3 inputs and two outputs.

2- Begin with the applet having all its inputs as 0's and see the resulted  zero's  outputs. Then, change the inputs A, B, and C using the mouse click between 1 and 0 volts buttons, and notice the outputs Sum and Carry. Repeat this step for all possible combination and write down the results in your truth table.
