A little help please

Got this sketch for controlling 3 banks off leds with pwm dinning, i need to amend the sketch i have to incorporate the second sketch could some on please help, i am guessing all the rtc from the first sketch needs replacing with the second sketch

After we have sorted this out i need to include a pwm fan driven from a temp input also a lcd touch screen sketch, any one up for helping

Thank you again

My scrolling finger hurts; could you go back and edit your first two posts and put the code into a proper box (use the # icon on the editor toolbar)

WilliamK · February 13, 2011, 11:34am

Indeed, that will also remove the 8) smiles from the code.

ah sorry thats how you do it, Now tried this code i thought it was all fine but when its dimming back down it get stuck on 248 pwm on both white and blues any ideas how i can amend
