I'm trying to read the state of a pin on the arduino and get the C# app to do a certain task, i know how to write to the arduino from the C# app, but i cant figure out how to get it to read the value of the pin ( high=1/low=0 ) from the serial and then make the app do a task ( ex. open a new form in the app or change the color of a box).
I just need the program to read the serial without showing the actual serial data, just do a task when it receives a 1 in the serial data, and do its task.
I have done a few c# programs before but only to send data over serial when a button is pressed or a event have been triggered.
Does anyone have an idea to do this, or could give me a few pointers how to do this? any help is appreciated
