}
It's working like a charm, the fade operates smoothly using timer1, the colors appear correct on led, but I can't fix the brightness part. Can someone provide sample code to do this?
If anyone else wants to use the code, I'm using an Arduino Mega 2560, please use the same PINs as mine since timers works only on 11,12,13 on this Arduino. (link with pin info regarding several Arduino boards)
I'm using a small Xbox 360 IR control (no numbers keypad), some HEX codes are left intact from the original sketch found on internet.
