 Tom Stanton did something similar, using Hall effect instead of a potentiometer.

+I purchased these because they appear to Windows as a Joystick, and are smaller than Arduino Leonardo. Since I only need one axis, via Hall Effect sensor, this device should suffice.
+According to the diagram, this can be converted between 5V and 3.3V device by shorting the J1 pads on the PCB.
+Description:
+  - The Pro Micro is similar to the Pro mini except with a ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on board and do away with bulky external USB interface.
+  - This tiny little board does all of the neat-o Arduino tricks that you're familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin, not to VCC.
+Features:
+* ATmega32U4 running at 5V/16MHz
+* Supported by Arduino IDE v1.0.1
+* On-Board Micro-USB connector for programming
+* 4 x 10-bit ADC pins, 12 x Digital I/Os
+* Rx and Tx Hardware Serial Connections
+Note:
+  - When you open the Arduino IDE software, pls go to the tool and choose the board "Arduino Leonardo"
+  - The acceptable voltage range is 5 to 9 V.
+Package included:
+  - Pro Micro ATmega32U4 5V/16MHz Development Board
