The issue I'm having is that the code does not appear to recognize that there is an input and nothing imputed from the serial appears in the file. I even added an LED "notification" to turn on when a new line is detected in the interrupt but it never turns on. This would mean there is something intrinsically flawed in my code. Any help would be great.
Thanks
