[sdiy] Incremental encoder to up / down counter or pots and an ADC

[Mike HEQX]

Thank you for illuminating this item Vladimir,

I really did like having the LED in the encoder. It looks great, but I 
also considered the metal shaft as a benefit long term.

I'll decide after I get the circuit up and running.
