Wifi shield UART

Hi,

In arduino mega what are the UART pins?

What options do I have?

Which UART do you want to use? Looking at the Mega product page, I see it has 4 (Serial0-Serial3).

Decide which one you want to use, look up on the product page for the pins, and bob's your uncle.

Oh, personally I’d avoid using Serial0 unless you are completely out of other pins. Leaving Serial0 free allows you to send troubleshooting messages back to the serial monitor during program development.

ok… this is my plan…

my material:
