Hello all,
I am pretty new to Arduino development and I wanted to post this as it may help somebody else.
I am developing an app that was working fine, and then it went literally haywire. After some careful investigation, I noticed that the "low memory" warning that I had been completely disregarding went from 80% to 85% and that destroyed the application.
In my case, it was a simple task to #ifdef out alot of Serial debug statements and I got back to 80% and all is well.
So keep this in mind if your low memory % is creeping up and things aren't working correctly.
If it's Ram you were low on, you can reduce usage by moving print text to program memory. For example,
Serial.println(F("this is a test"));
will result in the string being stored in program space, not RAM. Can make a big difference with wordy messages.

Which memory do you refer to?
Reduce the size and memory usage of your sketch – Arduino Help Center
Check this out. If you still have issues. Post your code in this thread for more suggestions.
Yes, it was RAM. Thanks for the post. I had seen the F in many examples and wasn't quite sure what it was for.
Good to know.
Cheers.
Lots of great tips. Thanks
