Iron Man Arc Reactor Clock (OLED Version)

This build is a remix of the one done by jerome95.

I built the reactor he designed and decided to modify it to add/replace some elements:

- Add possibility to connect also on Enterprise Wifi (SSID, Username, Password) in addition to domestic ones.
- Replace "fixed digits" display with 0.91 inches OLED display
- Smaller copper wire for coils, because looks better
- Several fonts available on display
- Boot logo
- Add touch sensor on a coil to toggle between fonts
- Add configuration interface (WiFi credentials, timezones, ...) using Serial connection on Arduino

There are 2 possibilities for center light:
- Basic blue diodes/Leds
- WS2812B programmable LEDs (requires soldering skills)
