my project Capacitive Sensing LED dimmer 12F1822 via PWM

One thing that did occur to me (during the night ) is that this type of power supply would limit the PIC's ability to provide a "high" output with any amount of current. So if you want to use those pins for something else you would want the active state to be a LOW or ground, or change the value of the 10K resistor to a lower value.

...

What if you just used VDD (pin 1) as your source, couldn't you then do as you please with that "regulated" 5V?

Edit: ok, I see where you're going. Even using a transistor on the pin, you're still limitted by what can pass through the resistor.

What if you use a higher wattage resistor?

Glue a heatsink on it.
