in my project, i have used PIC16F84 and 12 LEDs. colors of LEDs are various such as blue, green or red (for example 6 blue, 4 red, 2 green). for estability of voltag i've used regulator 7805.
my question is, what do you prefer about connecting LEDs to forward of regulator (12LED * 30mA = 360mA) or backward of regulator (that i have 14V)?
It's not a 'suggestion' it's a necessity
