+ 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 +3v
+ * 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 8
+ * SDI - to digital pin 14/15
+ * CLK - to digital pin 7
