Lilypad Arduino & LEDs

Development Boards Arduino

Hello,

I am a student and still pretty new to Arduino. I’m trying to sew some LEDs all over a dress for my upcoming project.

Does anyone know if you can sew more than 9 LEDs to the Lilypad, as this tutorial shows?(http://www.sparkfun.com/tutorials/312)

Thanks!

Well you could do a matrix of some sort, where one pin is configured as the source and the other is the drain. If you want more than one activated at a time, then you you will need to cycle through each LED you want on. With nine pins, you will get 4x5= 20 LEDs
