Hello all

I am using the attached VI for reading the data from the serial port every 5 sec but I am pressing the Stop button I am waiting for 5 sec to close the while loop anyone please let me know how I can stop the while loop when pressing the stop button without changing the wait timing 

any answer will be appreciate

You need to start with some basic LabVIEW tutorials because you code has so many glaring mistakes that it is not possible to easily solve your problem(s). Learn about proper state machine architecture. Look at the shipping examples and templates. Learn that index array is resizeable. Learn how to use event structures (they don't belong on the toplevel diagram or buried deep inside sequences! You have both! You only need one!). Learn how to avoid sequence structures. Learn about this function. Never operate on paths as strings. Do more error handling, etc.

(Your stop button is read first thing in each iteration, so if it is pressed right after that, you'll get one additional iteration.)
