I/O Expansion Shield for Arduino V7.1 Digital and Analog pins
Account cancelled 2014-11-14 19:21:46 2487 Views1 Replies Hi,
I have a small doubt about the I/O Expansion Shield board and its Digital and Analog pins. I am using a DFRobot Romeo V2.1 and for example, this one comes with 13 digital pins and the I/O Expansion Shield board also comes with 13 digital pins. Does this mean that the I/O Expansion Shield board can double the number of digital inputs up to 26? Or does it make a simple mirror of the pins in the Romeo board?
I am new with the I/O Expansion Shield board. I just test it with the blink example using pin 13 in the Romeo board and the pin 13 in the I/O Expansion Shield board is doing the same thing.
Is there a way to make this pins independent?
I haven't found any of this in the documentation, so I hope there is somebody here with the experience to help me.
Thank you

Romeo and I/O expansion shield are doing the same thing. It is a breakout of the I/O pins. But they are sharing the same pin. So it can't work independently.
What do you want to do with these device? If you need more I/O pins, you could try to use MEGA2560 Grey.CC
