This tutorial shows how to make a Soft Circuit Touch Sensor.
When pressure is applied to the sensor an LED lights up due to the variable "touch" pressure.
level: beginner. You will need basic sewing skills, and will learn basic electronic circuit.
fabric base. new, used, or fused recycled plastic fabric from our technique on Instructables !
conductive fabric. copper taffeta from Less EMF
conductive thread. Less EMF
foam. recycled from packing materials
embroidery thread. Thread Art
3v coin cell battery. DigiKey
battery holder. Digikey
LEDs. Super Bright LEDs or Radio Shack is good for local pick up in the US
needle nose pliers
a finger to press the sensor !
Step 1: Basic Circuit pattern
and the sketch of the pattern we will make [right].
The touch sensor will be the "switch" of our circuit.
When you touch it, the LED will turn on.
Let's begin !
