I have a project where I want 6 led's to fade in an out once triggered by and IR device. When I run the fading code by it's self all 6 led's behave as they should but once I introduce the IR code 2 out of the 6 lights will randomly blink and never fade like the others.
I've attached a video of this as well as the code, I'd appreciate any help....thank you!
Few will download the code as preferred method is to put it into the forum... I know file-sharing is efficient, but for now the forum spirit is to put it online here.
To assist, I have put it here.

The code as posted compiles, BUT around line #116 you have:
if (myCom == "one")
// Sequence 1
// fade in from min to max in increments of 5 points:
I suspect you need a "{" and a matching "}" to indicate a block of logic.
You should also study:
switch...case - Arduino Reference
The IRremote library uses Timer1 so you can't use hardware PWM (analogWrite()) on pins 9 and 10 when you use IRremote.
johnwasser, the lights that are having the problem are on pin's 11 & 3, pins 9 & 10 work fine.
Thank you mrburnette, this is my first post I wasn't sure which way to post the code.
I tried adding {} before and after the if statement but I get an error saying "expected primary-expression before'}' token."
Maybe they changed the default timer. Same effect, different pins.
I'm using an Uno would a different board work?
Yes. An Arduino MEGA 2560 has more timers and many more PWM pins.
