controlling 11 separate led circuits.

Other Hardware LEDs and Multiplexing

Welcome Dragonwire,

What you are doing ( all 11 circuits and more ) can be done with the Arduino chip and a couple of transistors, or a couple of shift registers.

First have a look at the sticky http://arduino.cc/forum/index.php/topic,97455.0.html

and some notes about LEDs

Then do a search on multiplexing LEDs , or I prefer to use TPIC6B595 shift registers to latch the high current outputs for long strings of LEDs , it can stand 50 volts ) Some of my projects use 2500 LEDs.
