Adding the DFRobot Relay Shield to the stack
Account cancelled 2014-08-09 09:01:21 1853 Views1 Replies I have the Arduino UNO R3, also have a Arduino Ethernet Shield stacked on top of that. I need to add the DFRobot Relay Shield on to the setup. In trying to put it on the stack I see a few pins not connecting so how do I put this on there, what is to happen with the missing pins. What is affected.

That is no problem, they are I2C interface.
If you don't use it, you can leave them. Grey.CC
