Well, I finally got the LoLin NodeMCU V3 ESP8266 Module working with the Arduino IDE! I think I was having so much trouble getting it working because there are so many variations of these ES8266 DevKits out there and the documentation is really lacking. Looking at the underside of this particular module it says “Use 9600 BPS” when really 115200 baud works. BPS…is that bytes per second or bits per second? Either way, the math doesn’t work out and 115200 baud was the answer. It’s interesting to me that there are a LOT of websites that have great projects but NONE that I have found have all the info in one spot; like setting up the IDE, setting up the USB-Serial driver for the particular Silicon Labs USB-Serial chip, programming the %$@%$! thing, etc. But this link is a good reference. I also found another really cool IDE for ESP8266 development called PlatformIO. You can add PlatformIO to Atom, which is an extensible open source editor of on top of VSCode, which is from Microsoft and it’s also open source and free (!). Apparently, MS is embracing aspects of Open Source! So, I’ve loaded the Platformio IDE for VSCode and I think I like this IDE better than the Arduino IDE.
