Hello Everybody!
I am new to this field.
I want to start a little project.
I have a question first.
I would like to use an arduino nano coupled with a nano shield I/O.
In that case is it possible to connect LEDs to the shield with female/female jumpers directly or i still need a breadboard to add resistors??
Thanks!
You still need to add current limiting resistors to the circuit somehow. A breadboard makes prototyping circuits very fast and easy. If you prefer, you could solder up a circuit on a piece of protoboard/stripboard instead or even just solder a resistor to one leg of the LED (perhaps insulated with some shrink tubing).
Welcome to the forum. I am not aware of any shield for a Nano but a big advantage of Nanos per se is that they fit on a breadboard. You will always need a small collection of jumpers of various types, but it's not a case of either/or, and a breadboard gives some firmness to what you are cobbling up.
I believe the shield in question is something like this:
www.gravitech.us also carries a bunch of nano shields.
