Signal Station
The station has plenty of opinions. Its signals only get two: 0 or 1.

Predict. Test. Build a rule.
Meet four logic gates, then choose gates for two station signs. A truth table records every possible input combination. Hints and retries are free.
These are ideal logical values, not voltage measurements or real wiring instructions. No batteries, tools or physical build are needed. Practice does not award grades or coins.

Predict, test every input combination, then explain. Practice, not a subject grade.
Fun fact: Three binary inputs have eight possible combinations. Adding one more binary input doubles the number to sixteen.
