Hi, anyone can tell me how to get value from arduino, currently i am using arduino and can only get string type through rs232 in vvvv. or can we convert string to value? because now i can get number but in string type.

hello fendi , for converting a string number into value you can use AsValue (String) for some arduino examples you can havea look at here and also here hope it helps

hmm, i tried using AsValue(string), in arduino part i am using potentiometer. it give loop value, and seems like AsValue(String) cannot receive very fast value. then i used delay in arduino code AsValue(string) can receive it but always give default value. because i need node that can receive value from potentiometer.
