Concept:

The concept behind my Unusual Switch project is to transform a regular room door into an innovative electrical switch. This unconventional approach leverages the movement of the door to control the on and off state of an LED light.

Demonstration:

Circuit:

Execution:

I set up a simple circuit with a resistor and an LED. Starting with a ground wire connected to the LED, which then connects to a resistor. To integrate the door into this circuit, I attached one wire wrapped in aluminum foil to the door frame and another, connected to 5V, similarly wrapped and placed on the door. A long strip of aluminum foil on the door’s moving part completes the circuit when the door is closed, lighting up the LED. Open the door, and the circuit breaks, turning off the LED. It’s a neat little setup that turns the action of opening and closing a door into an on-off switch for the light.
