This is a few little scripts to get the Raspberry Pi in that one vending machine on the third floor of the Media Lab to accept payments over the Lightning Network.
It uses Lit, which is an experimental Lightning node implementation developed by the Digtial Currency Initiaive.
This directory contains the Arduino source code that runs on the Arduino in the machine. It was taken from an older project before LN existed, so there's a few problems with it as-is. I'm making it cleaner and better some other time.
