Hi Windell –
Thanks for the advice! Good news: I think I just had the test circuit hooked up incorrectly. :) I verified the placement and orientation of all of the parts, examined the joints, and went back to my breadboard and started to wonder if I misread the pin assignments. I hooked it up fresh and it works now. The diagram looks fine, and I’m not sure where I messed it up, so no further feedback.
I’m very excited about this kit and the documentation. High quality, easy build, and very educational. Thanks again!
