Thank you 
My project is a 25 rgb leds single color changer with a random function.
I tried to build a scheme (based on this http://www.elcojacobs.com/wp-content/uploads/2012/08/shiftpwm_74hc595_RGB.png). Practically the 74HC595 shift works with a "data" connection (in 1st pin, out last pin), but in the code how can i control the single led?
I attached the scheme i build (only two shifts), but i think the "shift" has less pin that it should have.
Thank you for the big help!
