It appears that I need to use the same pins to connect two Arduinos together that are necessary for the barometer to work...
Hmmm, well I also want to use the WiFi shield on one of the arduino's so SPI is also out of the question I suppose.
Would connecting via serial be accomplished via digital pins 0 and 1? I've yet to find a wiring diagram and sketch example of this.
I suppose I could follow this example
Though this example should only allow one Arduino to send a message to the other and not allow bi-directional traffic, correct? I believe simply adding another cable between the two should allow for bi-directional traffic, no?
