led strip controller (TLC5940)

Hi. I would like to make such a led strip controller Moje boje z programowaniem i elektroniką: września 2014, but I would like to adjust the lighting time with potentiometer plugged in analog pin. How to change the code to extend the time to, for example, 3 minutes?

What's the time now?

Try experimenting with delayTime (line 8 ).

I'd guess that changing delayTime to 2 would make it run at half-speed, etc.

If that works for you, you can use the map() function to vary delayTime with the pot.
