NodeMCU RC522 and an electronic case

There are a hardware and a software but this is not all, there is also a case that holds all together 😀 and makes project look good 🙂
The Client wants a nice looking case and this is easy to understand. So new area for me, how to make nice holes for connectors, LEDs, switches and so, last time (with NodeONE) it wasn’t all good.
But today there is no room for failure! Let’s get to work!

Module and handler added to NodeMCU boilerplate @ GitHub
