I did see where Leah had 84 LEDs but she does say she had more. This is from her page: "Since my tank top is approximately 28" around and 12" tall I needed 84 LEDs. (Note! The pictures here show a different shirt with 140 LEDs spaced 1" apart.)".OK, so how could she do that?
I don't know if any of AVR ATmega processors available in 40-pin DIP packages are Arduino compatible.
QuoteI don't know if any of AVR ATmega processors available in 40-pin DIP packages are Arduino compatible. Really? After all my discussion of '1284 chips??
Just came across these in another threadhttp://www.adafruit.com/products/1260Like the LEDs/controller chip in the strips I mentioned above, but without the strip material.Connect them up with whatever wiring you were going to use.
