Unit #4-19

Learning Outcome

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

• build a 2-bit full adder

Review

• go over full adder

Lesson

• go over full adder truth table (see below)

Activity

• nil

Daily Assignment

• circuit - "2-bit full Adder"

  • copy 1 board in TinkerCad and make a copy to create this

  • 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

• for your schematic diagram, do not draw out each full adder, replace each on with a box (see below)

• build the circuit on your breadboard

  • once working, call me over to check

• for screenshots, DO NOT show me all 16 outcomes, please just do the following:

  1. 00₂ + 00₂ = 000₂

  2. 01₂ + 01₂ = 010₂

  3. 11₂ + 01₂ = 100₂

  4. 11₂ + 11₂ = 110₂ 

Extra

• • if you finish early, move to next circuit
