16 Laboratory Four Combining Gates: Half and Full Adders Objectives The main objectives for this laboratory are: Gain experience with logic circuits that involve multiple gates and chips Prototype the half adder and full adder circuits from the textbook Activities The first activity is to construct the one bit half adder circuit shown on page 154 of the textbook (included below). This circuit uses an XOR gate and an AND gate, which are on two different chips. Place these two chips on the breadboard and connect them as shown in the textbook. Place an LED on both the sum and the carry output so you can monitor the output from the circuit. Remember to use a 1K resistor with the LEDs so they don’t draw too much power. Once you have the half adder constructed connect the two inputs to the four possible combinations of ground and 5 volts and record the output from the circuit. Does this output agree with the truth table in the textbook?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
