Re: my project Capacitive Sensing LED dimmer 12F1822 via PWM
Ok Demon,
You got me thinking and as I did some more measuring I found that, with the 10K R, I had only 2 volts to the PIC. Which is ok but mabie a bit low. So I switched out the resistor to a 4.7 K and now I have 3.95V to the PIC and the current draw is 1.7ma (0.0017Amps)
I used one of these... http://www.eevblog.com/projects/ucurrent/
to measure the current
The zener is probably still not working too hard to control the voltage yet (not sure how sharp the zener voltage point is)
Any way I just wanted a simple way to power this ckt from the 12 to 15 Volt source battery.

These PIC's are like intricate puzzles just waiting for one to discover their secrets and MASTER their capabilities.
