I'm playing around with touchRead - one thing i'm noticing is that my values are going -down- when I touch the wire, not up. I have a wire attached to pin 23, and if i have a 10pf capacitor between the pin and ground, and my reads are consistently around 1400, and when I touch the wire, the reads go down to about 400.
Also - any recommendations for being able to sense touch through ~1/8" clear plastic - the wire seems to want physical contact? (Possibly with an led placed in the same spot).
