essayer blink

enf ait web client! e autres à corriger

depuis: http://blog.rexave.net/wp-content/uploads/2013/10/ethercard-master.zip

premier essai
lu: http://arduino.cc/en/Tutorial/WebServer
1) voie série ???
2) sans doute modume 5100
3) pas d'erreur!
4) ir ethernet shield à pin 13, douteux, c'est la diode!

client(juste ajouté pin 10 comme CS de la carte ethernet)

signaler l'ambiguité obligation indiquer pin 10 (au lieu de 8)

essayé exemple webclient, Ok, dhcp, etc .. convient pour Dazibao et Sms2Go?
essayé udplistenner, pin 10, OK.
