my project Capacitive Sensing LED dimmer 12F1822 via PWM

[Heckler]

Just wondering if anybody has taken the time to bread board up the circuit and see how it works?

If you do build the circuit I suggest you lower the value of the Resistor in the Zener ckt to around 4700 ohms.
(Assuming you are trying to drive it with 12 Volts)

I still need to learn about how to best design a small circuit board with an included touch pad. I still am unsure if I need a surrounding ground to make the touch sense work better.

My testing shows that it does not seem to make much difference.


Here is a link to a video of my circuit working

(the video is in my drop box so I am not sure how this will work, its about 8 meg)
