+/* Temporarily disable the decoder
+ *  
+ * This example is part of the the IRsmallDecoder library and is intended to demonstrate 
+ * a possible usage for the enable and disable methods of the decoder.
+ *  
+ * How to use this sketch: 
+ *  - Connect the sensor (see library documentation);
+ *  - Uncomment the #define for the desired protocol,
+ *    (leave the others as comments, only one is allowed);
+ *  - Upload the sketch and open the serial Monitor;
+ *  - "Teach the Arduino" which key you want to use to disable the decoder;
+ *  - The selected key will temporarily disable the decoder;
+ *  - Any other key on the remote will toggle the builtin LED;
+ *
+ * In this example it's assumed that the board has a builtin LED and the IR sensor is 
+ * connected to digital pin 2, which must be usable for external interrupts.
+ * For more information on the boards' usable pins, see the library documentation at:
+ * https://github.com/LuisMiCa/IRsmallDecoder
+ * or the README.pdf file in the extras folder of this library.
