Nano + I2C 20x4 LCD + encoder

I setup some simple hardware debounce and then dropped in some code to read the push button the rotary encoder. The hardware debounce works fine so I am happy with the results.

The next step will be to write some code to use the encoder push button to change the cursor between the Hz, KHz, and MHz fields of the frequency display.
