Components used:

  • 7-segment display (anode)
  • BCD to 7-segment Decoder (7447)
  • 10K ohm resistor (pulldown resistor for DIP switches)
  • IC numbers: 7408, 7486, 74153, 7432

🡪one IC of each of them except for 74153 (4x1 Mux) 2 ICs required.

  • Male-Male Jumper wires
  • Adapter Power Supply (5VDC) (here for the power supply we will use Arduino)
  • Breadboard
  • DIP switches

Our ways for optimization

Obtaining complement of B from the XOR instead of buying another IC (7404) to give me the complement of B.

1

Obtaining Increment operation by using the input carry in the 4-bit binary adder, instead of using another integrated circuit to achieve this function.
