+  Digital Pot Control
+
+  This example controls an Analog Devices AD5206 digital potentiometer.
+  The AD5206 has 6 potentiometer channels. Each channel's pins are labeled
+  A - connect this to voltage
+  W - this is the pot's wiper, which changes when you set it
+  B - connect this to ground.
+
+ The AD5206 is SPI-compatible,and to command it, you send two bytes,
+ one with the channel number (0 - 5) and one with the resistance value for the
+ channel (0 - 255).
+
+ The circuit:
+  * All A pins  of AD5206 connected to +5V
+  * All B pins of AD5206 connected to ground
+  * An LED and a 220-ohm resisor in series connected from each W pin to ground
+  * CS - to digital pin 10  (SS pin)
+  * SDI - to digital pin 11 (MOSI pin)
+  * CLK - to digital pin 13 (SCK pin)
