student designed project (ap physics) digital logic and boolean algebra exercise

GK-12

Student designed project (AP physics)

• Digital logic and Boolean algebra exercise.

• IC logic gates brought from Stevens were used in making simple circuits.

• Students demonstrated models with AND, OR, XOR, NAND etc.. gates.

• Model half adder constructed by students along with their presentation to demonstrate principles to rest of class.

Circuits

Half adder

wikipedia

Advised students with end of term projects and provided guidance for two groups working with digital circuits.

• George Boole

• 0 or 1, Cannot be partial

• 0=0v, False

• 1=5v, True
