Hi all,
I brought Ethernet Shield for my Arduino.
How can I find MAC address for the same ?
Is there a way to find MAC address without connecting it to internet or Router ?
Can I find it using usb connection to my laptop ?
Thanks in advance,
Regards,
Swaroop
If it is a official Arduino ethernet shield (w5100 IC), then it has no mac address assigned. You can assign it any unique address. The most common is DEAD BEEF FEED.
byte mac[] = {0xDE,0xAD,0xBE,0xEF,0xFE,0xED};
Thanks. I bought official Arduino Ethernet Shield R3 ( based on W5100 Ethernet chip).
I will try that out and let you know.
The reason I asked was, the Arduino Yun's I had , had predefined MAC addresses.
