/*
 * ------ [4-20mA_01] Current Loop Basic Example --------
 *
 * Explanation: This sketch shows how to use the most important
 * features of the 4-20 mA Current Loop Board in Waspmote. This
 * standard is used to transmit information of sensor over long
 * distances. Waspmote uses analog inputs for reading the sensor
 * values.
