Nice project.

I notice what I think is the same chip mentioned earlier for 4 bucks each (TLC5941NT) for only  1.62 each with min order of 1.

I ordered some TLC5940s from these folks for ~1.80 each .. now I wish I read more and got these.     But the price at this place sure seemed alot lower than mouser .. so I figured I pass it along.

This place will accept a reasonable offer for 5940s

I've got 25 coming (far more than I need so if someone in the uk wants a couple let me know).  Cost me less than I could find in the uk so I justified the postage and ordered a few extra.

That is really cool. hmmmm.... I will keep this in mind for any projects that I may or maynot having coming up.

Hi,

My LED shield works fine, but the analog inputs on my Arduino Uno board seem to pick up random values. If I ground the analog input pin, analogRead() sometimes returns zeores and sometimes very high values. I have tried with an external power supply for the leds, and tried different delays in the loop. But nothing seems to help.

Here you see a typical sequence of values from the grounded pin:

--------
0
0
1
1016
3
0
0
1
1016
4
0
0
--------

Any ideas?
