Hi, Rich & Aaron,
A very easy way to build an LED bargraph or dot meter is with the LM3914 IC. I am using this to trigger my solid state relays (for a vaiable load controller using hot water heating elements) at any selected voltage indicated by a "lit" LED. I also have a potentiometer on the DC input to set the meter level to start at basically any voltage which then is linear throughout the range. I have 2 IC's which sequence 15 LEDS, first 5 green, 5 yellow, 5 red. Just thought it might be something for you to check out. Here's a link

If that doesn't work just google search LM3914. Good luck with your projects, it looks great. Dave B.
