Hi,
I'm new here so I don't know whether it is appropriate to ask a related but oot the same question here, or should I start a new thread. Please, advise me.
My question is rather simple one:
Can I freely use pin 4, if I don't plan to use SD interface ?
I need pin 4 for some other taks. I do not need SD interface (and there is no SD connector on my Ethernet shield).
