Start by predicting the output of circuits with AND, OR and NOT gates, then design your own circuits. Apply your understanding of logic gates to build an adding machine.

Learn the rules that govern the behavior of three basic logic gates.

Combine these gates to build up more interesting circuits.

Logic Gates

AND Gates

OR Gates

Combining Gates

NOT Gates

Choose components so circuits follow specified behavior.

Build circuits from scratch using the three basic gates.
