Unit #4-19

Learning Outcome

At the end of this lesson, you will be able to:

  • build a 2-bit full adder


  • go over full adder


  • go over full adder truth table (see below)


  • nil

Daily Assignment

  • circuit - "2-bit full Adder"
    • DO NOT do the normal Fritzing diagram
    • join with another student if you want to (they already have a full adder!)
    • just ground your Carry In, so that it is always zero
  • build the circuit on your breadboard
    • once working, call me over to check
    • take a picture of your completed breadboard and upload it to your notebook
  • Note: you should be uploading 2 things to your notebook:
    1. truth table
    2. picture of completed real world breadboard


    • if you finish early, move to next circuit
