II. Full Adder (Logic Gates)
A. In Tinkercad, we will implement a Full Adder circuit using basic logic gates. See the diagram below from the lecture slides:
For Tinkercad, the following parts will be needed:
(1x) Breadboard
(1x) Power supply
(1x) 7486 (Quad, 2-input XOR gate)
(1x) 7408 (Quad, 2-input AND gate)
(1x) 7432 (Quad, 2-input OR gate)
(2x) 330 ohm resistors (for LEDs, from cathode to ground)
(2x) LEDs (one red, one green)
The "Sum" output will be represented by a Red LED, and the "Carry" output will be represented by a Green LED.
B. For your input wires, indicate the wire color for the X, Y, Z inputs. In the example below, X is represented by the green wire, Y by brown, and Z by grey.
