Concept
This piece transforms a simple circuit into a puzzle. The connection between the switches is not obvious. The user needs some time to figure out what makes the LEDs light up.
The red LED changes brightness as you turn the potentiometer. Also, pressing only one of the push buttons does nothing you have to discover the specific “sweet spot” gesture. Only when all conditions align do the LEDs respond.

Future Improvements
A single puzzle could evolve into something far more complex by layering additional challenges:
-
- Timing urgency: Buttons must be pressed within 2 seconds of entering the sweet spot, or the blue LED only stays lit for 3 seconds before requiring you to solve it again. This adds urgency and makes the victory feel earned rather than permanent.
- Pattern memory: The blue LED blinks a simple pattern (like short-long-short) at startup. Users must recreate this rhythm with the buttons while in the sweet spot to unlock, transforming a spatial puzzle into a temporal one.
