I have been trying to get the value of a few sensors on C# from Arduino and pass a value from C# to arduino for a motor. That is
Sensors---> Arduino ----> C#
C#---> Arduino --- > Motor
I am able to do these two things individually, but not together. The reason being that the serial is able to hold only one set of data at a time. Is there a solution to it, or will it be that I will have to use one arduino for sending and one arduino for receiving the data. Please help me through this situation.
