I decided to use a paper and graphite(conductive material)  as a switch.

First, I built a simple circuit with LED, and checked if it works.

With pencil, I drew two points and connected them to make current flows from one point to other point.

To check the LED brightness, I drew 4 lines with different length.


The shorter length, the brighter light.

The longer length, the dimmer light.

Which means different length can control the strength of brightness.
