This video demonstrates how to wire and program LoRaWAN nodes to The Things Network (TTN) using both a common Arduino with an SX1276 breakout, and a Feather MO LoRa coupled with a DHT22 sensor. These demonstrations use the "MCCI LoRaWAN LMIC" library for the Arduino IDE. If you wish to replicate, you will also need to sign up for a free "The Things Network" (TTN) account at www.thethingsnetwork.org/ .
The nodes demonstrated here will be used for testing radio coverage for a LoRaWAN gateway planned for Xerocraft (Tucson, Arizona Makerspace) in a couple months (February - March, 2021).

Please note that this video does not cover TTN's fair use policy. If you use The Things Network (free public community LoRaWAN network), the following fair use policy applies:
The uplink airtime is limited to 30 seconds per day (24 hours) per node.
The downlink messages are limited to 10 messages per day (24 hours) per node.
Source: lora.readthedocs.io/en/latest/
As such, keep in mind that the code referenced here may violate this policy if left running 24-hours a day. I haven't yet crunched the numbers on the referenced code-- maybe something for a future video.
My sincerest thanks to Robert Lie (MobileFish); Andreas Spiess (Guy with the Swiss Accent); and Brent Rubell (Adafruit) for their own excellent demonstrations and documentation that helped non-electrical engineers like me get this far, and to both Adafruit and Andreas for always replying to my comments and questions. The following are highly recommended resources for noobs like me:
