Hello Sirs -

Continuing to follow along. I have created a small chunk of "programmable hardware"  

Many header pins to allow me to play with different ideas presented here. Since its only resistors I can determine which polarity I use for the power pins.

What a great forum this is!

Thanks so much!

With 2.5k pull up and 470 in the "series ladder"

Ain
3.3
1.19
0.91
0.53

So should have problem with interrupt to a low.

Are these deltas able to be resolved ? (Admittedly a noob question. I am off to learn more about A/D)

Unless I see an exception thrown by you gents - I am off to rotary encoder I/O board

Cheers!
