I have written a program for pic controller. The program has two conditions. In condition 1 I power on the led continuously and in condition 2 i blink the led with some delay. I found that if i switch on continuously the intensity is very less whereas while toggling the intensity is more. Why this is happening?
usually it is the other way around, I am suspicious that you are witnessing an optical illusion where your eyes arn't adjusted to the light when it turns on so it seems brighter
Can you just tell me is it possible that suppose i have 20 outputs can i connect 20 leds. I mean to is it possible to drive 20 leds? How to know what is the limit?

I should imagine it's an optical illusion... 1k resistor LED and 5v rail... 3mA will just light the led, so the continuous LED will appear dim, whereas the pulsed LED (depending on frequency ) will alert your eye to the LED more..
