How it works
Two numbers in [0-15] are converted into 4 bit binary numbers. For example, A = 8 and B = 3: A = 1000 B = 0011 The two numbers are then added.
How to test
Enter the numbers using the switches (inputs 0-3 for A (LSB=0), inputs 4-7 for B (LSB=4)) and observe the ouput (LSB=0)
External hardware
Switches for input (8), LEDs for output (5).
