Thanks, Mike!  Exactly what I needed.

analogread()?  If so, what are the analog I/O positions that map to these connectors (A0-AX)?

Thanks.

Any "best practices" for handling change-based notification of sensor/switch events?  I'm currently just using a loop with a small delay, then comparing previous value to current value, and dispatching an external event when there is a delta.  I've added some deadbanding on the analog sensors to avoid excessive chatter also.  Just wondering if there is a "non-polling" way to do this?  Thanks!  Really digging the device. Makes for fun demos. ;-)
