I am currently doing a project that will include power line communication using two mamba shield: https://www.sparkfun.com/products/10918 I am using the Arduino uno R3.
My main problem is that I foolishly went ahead and bought the two mamba shield's before doing too much research on them. Turns out the internet is pretty much empty when it comes to examples/guides. Other breakout boards I have bought I managed to get working through trial and error and looking through example codes, which I can't do with this one as there isn't enough out there.
So I am just looking for anyone with experience using them just to point me in the right direction. Ultimately they will be used to send two sensor readings from one Arduino to the other. With all communication going in the one direction.
