Unconventional Switch: Catan Robber Tracker

In Catan, the robber piece can be cause for alarm. It blocks resource production and can even steal your cards. For our unconventional switch, placing the robber on specific hex tiles lights up an LED. Players can think of it like a danger light. When the light turns on, the robber is directly affecting them. Our switch can also use LEDs of different colors, allowing for a clear distinction between players. To achieve this, our switch uses a 5V power supply hooked up to a laptop, three alligator clips, a 100Ω resistor, a green LED, a blue LED, a breadboard, a robber piece from Catan wrapped in aluminum foil, and at least two hex tiles from Catan also wrapped in aluminum foil.
