like I said, I have an led that needs to be off when the momentary switch is off, when the switch is held I want the LED to fade in and out. currently the fading works when the switch is held but the led stays on when the switch is off. my code is attached, thanks in advance

OK, first things first.

You need to go and read the forum instructions so that you can go back and modify your original post (not re-post it) - using the "More -> Modify" option below the right hand corner of your post - to mark up your code as such using the "</>" icon in the posting window.  Just highlight each section of code (or output if you need to post that) from the IDE and click the icon.

In fact, the IDE itself has a "copy for forum" link to put these markings on a highlighted block for you so you then just paste it here in a posting window.  But even before doing that, don't forget to use the "Auto-Format" (Ctrl-T) option first to make it easy to read.  If you do not post it as "code" it can easily be quite garbled and is always more difficult to read due to the font.

It is inappropriate to attach it as a ".ino" file unless it is clearly too long to include in the post proper.  People can usually see the mistakes directly and do not want to have to actually load it in their own IDE.  And even that would also assume they are using a PC and have the IDE running on that PC.

Also tidy up your blank space.  Do use blank lines, but only single blanks between complete functional blocks.

I suggest you get the Arduino Cookbook, your solution is published.  Also there is a lot of line that will help you with this project.  It is a good project for a beginner.  This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!
