Re: Arduino + MCP9600 + thermocouple help needed

Thanks very very much for that.
Found
MCP960X-Data-Sheet-20005426.pdf
and suspected it had value.  Now I know "it's it" I will spend time on
it over time.

might have come up on searches - tenuous maybe - but I didn't register

This is all so new to me.  Before yesterday morning I didn't know of
"pull-up resistors", for example.
I altered a circuit to test this

"Arduino / embedded-devices - the learning begins"
Didn't take a video, but the LED is indeterminately going on and off
when the button is not being touched.  etc, etc.

Better try to get back to sleep for now.
Thanks.
