Hi all,
I am trying to figure out what digital i/o are available for my sketches if I use the ethernet shield. According to this reference page http://arduino.cc/en/Main/ArduinoEthernetShield pins 10,11,12,13 are usded for SPI communication with the ethernet shield. But I can see some other pins marked with an asterisk (pins 3,5,6) and that looks suspicious.. are they still available as general i/o?
