 *  ------Waspmote Power Getting Battery Level Example--------
 *
 *  Explanation: This example shows how to get the remaining battery 
 *  level.
 *
 *  Warning: it is recommended to get the remaining battery level without
 *  USB connected to Waspmote, due to when USB is connected and battery
 *  is medium-full charged, the measurement is not valid. Only when battery
 *  is almost dead the measurement will be valid.
