For Physical Computing class, I had to come up with a creative idea for a switch. I sewed a switch out of conductive tread that is activated with pressure.
Here is what conductive tread looks like:
Here is a great video that explains it all:
Here is what the interior of my switch looks like.
I sewed the negative wire to this side:
Then I sewed the positive wired to this one:
Then in between the two, I put a resistor material:
The switch in thus activated with pressure. The more you press, the brighter the LED is.
In the following weeks, I will sew a street gang style fabric patch with LEDs. When you will hug someone, the switch will activate the LEDs.
