Connect the Circuit Playground to The Things Network using a LoPy

[PiAir]

Small project to connect the Circuit Playground (CPG) to a LoPy Node using the TX/RX serial connection and then send values from the internal CPG sensors to The Things Network.

All code is available online, could probably still use some cleanup, make it more resistant to errors etc.
See this post for all the info, and you can find the code on github.
