Question
Two car garages have a common gate which needs to open automatically when a car enters either of the garages or cars enter both. Devise a circuit that resembles this situation using diodes for this situation.
✓

Answer

As car enters in either of the garages or both, the common gate opened automatically.

This means that if any one input is high, output will high otherwise low. The device is shown like this:

So, OR gate gives the desired output.

ABY = A + B
