Just some thoughts that may help someone. To get started I would recommend the Nano. You just need it , a usb cable, and the IDE downloaded. The Nano has a usb chip on the module. No hassles about connecting. The pro mini does not have a usb chip, but is otherwise the same. To use it you need a usb to TTL adapter. I bought an adapter with a FDTI232 chip and could not get

Today we use LVD (low voltage differential) logic, at low voltage levels; before that, there was HVD (RS-485), ECL, TTL, DTL, and a few odd items like the high-voltage DTL of MC1488, and CML (current-mode logic?) and such. But 'WAY back there was a system with high power supply voltages (about 450V) and very peculiar antenna-based sensing
