Hello everybody, I am new to forum and ive been starting using labview for about a month (lol), and today made a reverse counter that woul send a number 1, to my arduino uno, when counter reached 0 or less, but for some reason it seems that labview isnt sending any data to it, the Rx led never lights up, and the outputs are for a buzzer and a led. I was searching through web, but nothing seems to match my problem, and the "similar" ones are way too complex compared to my problem, so i maybe did something wrong in the labview code or arduino, can you help me verifying it? Thanks.
