 * Sensor technical specification
 *   GP2Y0A21YK0F (default)
 *     Range: 10cm ~ 80cm
 *     Connector: 3-JST
 *     This SHARP distance sensor bounces IR off objects to determine how far
 *     away they are. It returns an analog voltage that can be used to 
 *     determine how close the nearest object is.
 *     The analog voltage out will range from 3V when an object is only 
 *     4" (10 cm) away and 0.4V when the object is 32" (80 cm) away.

 *   GP2Y0A02YK
 *     Range: 20cm ~ 150cm

 *         Improvement: Library renamed from Infrared to IDMS to solve library
 *                      name conflict with oficial Arduino libraries.
 * 
 * 2015-05-14
 *         Experimental version.
