A quick note that we discussed the workshop last Wednesday. Using the previous workshop as a reference, we contemplated the possibility of moving to a NodeMCU kit, thus allowing some wireless action. It was suggested that people are likely to be familiar with using phone apps. We debated the fact that using any WiFi project will require using a number of "black box" libraries that such an intro course cannot go into. Shown we stay on the bare metal level?
Naturally, a NodeMCU can easily fulfil the need of the projects presented in the earlier workshop, leaving open the option for either a follow-up meeting or a documented project left as a take-home exercise for the student.
