High precision timing on Arduino for serial communication
However the interval timings between successive time stamps appears to be increasing over time, affecting my plotting. … time=(time*4);
//Print in a file for simulation
//Serial.print(time);
//Serial.print(" ");
Serial.print(fanalog0,5);
Serial.print("\n");

Arduino time keeping using millis() is not accurate or correct?
Am I correct in saying that the Arduino delay function affects the time keeping using millis()? … runs over and over again forever:

Serial.println("");
