- 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)
