How to if(newSerialString) resetFunction and then run newSerialString

[adamelli]

Right now, I have if-statements set-up with if (Serial.available() > 0) resetFunction();

Instead of calling the resetFunction whenever data is entered into the serial monitor, I want it changed so if a new string is received, then it will call the resetFunction.

However, data is received serially. So the incoming new string replaces the old string. I don't know how to store the old string. How would you store the old string?

In the absence of your code, my best suggestion is strcpy

I used strcpy, and some other things, and now it works.
