HowTo: Arduino + RFID Reader + Ethernetshield

19. Januar 2013
admin 19. Januar 2013Mein Home Security System ist wieder einen großen Schritt weitergekommen.
Es ist jetzt möglich den Status auf einem vom Arduino bereitgestellten Webserver auszulesen.
Dank dyndnss.net könnt ihr meinen Arduino auch Live verfolgen.
(Ein Tutorial wie man DynDns einrichtet, ist auch in Planung)
