/* * ------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. * * Copyright (C) 2011 Libelium Comunicaciones Distribuidas S.L. * http://www.libelium.com * * This program is free software: you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation, either version 2 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
