In this tutorial you will learn how to turn any conductive surface into a capacitive touch sensor. This project illustrates how to use capacitive touch to turn on a motor (fan) and neopixel. In this example, all of the components were custom designed and built specifically for this application. Since this method can be used for many different applications, this instructable will cover the behind the scenes making of the circuit and code.

Step 1: Step 1: Gather Materials

Picture of Step 1: Gather Materials

The main components needed for this example are:

Arduino Uno
12volt fan (3 inch)
small breadboard
neopixel
a lidded jar
wire mesh
confetti
12volt wall plug adapter
22k ohm resistor
100k ohm resistor

The video above illustrates the first stages of prototyping the capacitive touch switch. The ball jar and foam sqaures are a stand-in for the final product, they do a great job of illustrating the animation that will happen in finished piece. Although the conductive fabric is acting as a stand-in for the actual switch, you can easily imagine that if it were hooked up to the metal lid of the jar, it would act the same way.

Cool!

Looks like your vimeo link is broken. :O

This will surprise a lot of curious people(like me) when they touch the base.

Can you change your title to something a bit clearer? This is a very useful project, but I'm afraid it'll be ignored if your title is too clever.
