Beginner Open/Closed Principle Signal Circuit Solution

Stage 2 Best Circuit Setup

Activate the Inductive Switch Via the Green Signal Source

The penguin from the green source signal can trigger the green circuit that is connected to the orange endpoint. Make sure not to get confused about the color and position of the inductive switch; if a penguin walks on it and activates it, it will activate the matching circuit wherever it is linked.

Link Signal Sources to their Appropriate Endpoints

The circuit board of stage 2 will have two endpoints. Check the color of the signal source (where the penguin is standing) and find the endpoint with the same color; this should be its endpoint. To complete the debugging process, ensure that the circuit is connected to the same color.
