# Lies mich! :)
Autologinscript für die Anmeldung in Wohnheimen, welche über eduroam ins Internet gehen.
Achtung aktuell KEIN https, sondern nur http!!!
Autoren: kilobyte22, bambi
# Notwendige Hardware
- ESP8266 (gehen natürlich auch Andere, dann müssen nur die jeweiligen Header nur angepasst werden
# Einrichten
- Über die Arduino IDE die Datei credentials.h mit Logindaten für WLAN und Login füllen
