HiLetgo NodeMCU

One of the 1st wifi-enabled boards I tried. Here are my observations: you need additional libraries – https://github.com/esp8266/Arduino (lesson: install libraries) pin numbers are not numeric once the libraries are imported, pins can be referenced as D2, A0 etc. (Please note: D2 != 2) See also We have a course for this board here
