Software Programming/Loading

Arduino V2.0.0-rc7 (incl. esp32 hardware catalogue and necessary libs)

Three parameters must be updated inside source:

• Brick API Key
• Wifi SSID
• Wifi password

Possible improvements

• Implementation of Wifi Manager to avoid hard coded Wifi credentials
• OTA Programming (if bugs inside Arduino IED are closed)
• Configuration of Brick API key outside of source
