Simple question about serial write and read for Arduino Labview interface

[zache7]

So I am controlling two stepper motors and have written an Arduino IDE code that includes microstepping and prompts the user to enter numbers 1-6.  Each of these numbers triggers an if statement that turns on one of the motors for a determined distance.  The serial monitor on arduino works perfectly but I wish to interact with the serial monitor on LabVIEW in the same exact manner.  I have been messing around with the "Continuous serial write and read.vi" in the example programs.  The VI works to a certain degree but once I type 1 in the write command path, the program will keep sending the command over and over again until the program is stopped.  I need it to send a single command, and wait for the next user input without queing additional commands.  I can provide the LabVIEW and Arduino files if needed.

You'll want to look into Event-Driven Programming in LabVIEW.
