The TLC5940 is a 16-channel, constant-current sink LED driver. Each channel has an individually adjustable 4096-step grayscale PWM brightness control and a 64-step, constant-current sink (no LED resistors needed!).
This library supports daisy-chaining multiple chips together. I haven’t tried this library on anything but a Diecimila, so YMMV.
The most useful functions:
Tlc.analogWrite(channel (0 – 15), value (0 – 4095), chip (0 – n));
Tlc.analogWriteAll(value (0- 4095), chip (0 – n));
Tlc.setPWMperiod(PWM period (0 – n) milliseconds);
