    Hi

    Ive got 2 of these chips daisy chained and connected to my Arduino.

    Im an electronics newb and figuring things as i progress, but i have a question on the TLC5940 pins. Its spec'd to be able to sink a max of 120ma current on each output pin.

    I need to wire 4 led's on one pin, rated at 3.2v 20ma each.

    Im unsure of how i should connect the led's, supply voltage and the current resistor on the TLC5940.

    any help?
