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:

You can find LED and conductive tread on Aniomagic. Here is a great Website to know more about fabrics and electronics, it is called How to get what you really want.

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.
