Uses SparkFun MicroView dial widget and a Quadrature encoder

- encoder code from http://www.circuitsathome.com/mcu/reading-rotary-encoder-on-arduino with fixes (handles pins other than the first ones on a port, and doesn't double step)
Edit rotodial.ino and change the values of ENC_A ENC_B ENC_PORT ENC_SHIFT for your encoder pins. The sketch as is uses pin 2 and 3, which are on Atmega 328 PORT B, and need SHIFT=2 to shift down to bit zero from bit 2.
Turn the rotary encoder and the MicroView Widget will follow.
There was no license on http://www.circuitsathome.com/mcu/reading-rotary-encoder-on-arduino but assuming it's MIT, license, this is too:
