I have 144 LED's in 24X6 LED array. These are high power 3W LED's. After searching I found out that TLC5940 can be used to increase the PWM pin's on Arduino.
I'm not sure how to connect TLC's output to CAT's input. Since the TLC is current sinking driver how can I use it to control LED brightness by sending signal to the PWM Pin of the CAT? If I connect TLC's output to CAT's PWM input will it work?
