Lots Of LED shields with SMT, 3MM, 5MM, 10MM LEDs available in 4 colours:
red green blue white
This is Lot-Of-Leds multiplexing LEDs shield with 126 LEDs made in 14x9 matrix.
This shield originally was developed by Jimmie P Rodgers and you can find his
original project and Arduino libraries here
When we saw this shield for the first time we fell in love with it, it was so simple
and nice to play with, especially when we saw how Super-Awesome-Sylvia
assembed it :) What we didn't like on the original design was that it uses only
3mm LEDs, so we made another one with 5 mm and 10 mm LEDs, and one complete LOL
with embedded Arduino called LOL-TEXTILE which is 30x20 cm and can't be attached
to the back of your clothes.
