A while back I saw an article on how to daisy chain LEDs using a bread board. Of course, now that I need it I can't find it. Anyone knows how to daisy chain multiple LEDs? I need to control about 30 LEDs individually. Any other suggestions on how to easily control that many LEDs?
Use two Texas Instruments TLC5940s! The chips allow you to control the intensity of 16 LEDs per chip. Theres a library for controlling them but if you get stuck, just ask.
You could start by heading to the arduino.cc page and going into the Reference section followed by clicking the Libraries link. That page has a link to the TLC5940 library that was suggested to you and includes a handy link to the manufacturer's datasheet for learning more about the part.
