Yet another dumb question? Answered
Hi Guys, ( I am prickly)
I am really excited as I'm going to make my first project ever that includes resistors. I needed some help regarding (no not resistors) batteries. I need to chose which battery to use either 2 AA batteries (3 LED's in parallel) or a 9v battery (3 LED's in series). I want to choose the way in which the LED's will be brighter for longer.
Thanks in advance
