+ * Demo for RF remote switch receiver. 
+ * This example is for the new KaKu / Home Easy type of remotes!
+ *
+ * For details, see NewRemoteReceiver.h!
+ *
+ * With this sketch you can control a LED connected to digital pin 13,
+ * after the sketch learned the code. After start, the LED starts to blink,
+ * until a valid code has been received. The led stops blinking. Now you
+ * can control the LED with the remote.
+ *
+ * Note: only unit-switches are supported in this sketch, no group or dim.
+ *
+ * Set-up: connect the receiver to digital pin 2 and a LED to digital pin 13.
