RC..cap to ground...R to pic pin....led across C...R is the current limiting
resistor for the led and is also used in the RC timing calculation '1' turns
it on '0' turns it off...or C to Vcc where '1' turns it off and '0' turns it
on. Just play with values of C and the off/on/off of the pic to get what
your happy with. Or you could pwm your pic pin.

Subject: [OT]: Blinking LED softly....


How can I soften the blinking of an LED so that it doesn't go on and off so
abruptly? Is there a way of doing this with just an RC and no transistor?

I am blinking an LED with a pic port and I can use either high or low to
light LED.

Thanks

John
