-  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)
