Connecting Geiger Counter for Arduino and Raspberry Pi to radmon.org

/*
 *  ------Geiger Tube board (Arduino Code) Example--------
 *
 *  Explanation: This example shows how to get the signal from the Geiger Tube
 *  in Arduino, we use one of the Arduino interrupt pins (PIN2).
 *  We count the time (ms) between two pulses of the Geiger tube.
