Hello everyone, I am new to arduino.I have been in trouble for quite a long time with this. I have a project which consists of obtaining Labview serial input of a Spectrum .I need to take each value (x,y)=(dB,Hz) of the real time Spectrum and check if it is over a reference value. This Spectrum input is sent as a string at my Arduino Uno. I know I have established communication. What i don't know is how i would be sure that the first two values that come to Arduino are dB and then Hz (or the opposite) and if that's the way that the values are arriving to Arduino how i am going to store it as a double (or float) and deal with each seperately.
I am looking forward to hearing from all of you. You would be of a GREAT help ! Thank you very much in advance.
