error: expected constructor, destructor, or type conversion before 'class'

Hi rlandmet

AEID
// Arduino Electromagnetic interference detector // Code modified by PAtrick Di Justo, based on // Aaron ALAI EMF Detector April 22nd 2009 VERSION 1.0 // aaronalai1@gmail.com // // This outputs sound and numeric data to the 4char
#include <SoftwareSerial.h> #define SerialIn 2 #define SerialOut 7

If that "AEID" is in your progam file on the first line (and did not creep in when you posted the code), either delete the line or put "//" before it.

Regards
