Tell us about yourself!
hello there!the fact is that you can decide the current draw, because you know which is the starting forward voltage: in the latest project i made (always with the same kind of leds), i measured all the forward voltage of the leds, discovering an average of 3.5V-3.6V. So, taking into consideration that mine was just simple project, all the calculations were pretty good. (my leds were the classic 5mm, no fancy things)
happy to hear that!uhm...laptop ram...time for another keychain XD
