+ * Example: Gauges
+ * This example prints Signal, Audio In, and Audio Rx ADC 
+ * Peak strength to the Serial Monitor in a graphical manner.
+ * Connect the HamShield to your Arduino. Screw the antenna 
+ * into the HamShield RF jack. Plug a pair of headphones into 
+ * the HamShield. Connect the Arduino to wall power and then 
+ * to your computer via USB. After uploading this program to 
+ * your adruino, open the Serial Monitor. You will see a 
+ * repeating display of different signal strengths. Ex: 
+ *
+ * [....|....] -73       
+ * Signal 
+ *
+ * Uncheck the "Autoscroll" box at the bottom of the Serial 
+ * Monitor to manually control the view of the Serial Monitor.
