[ThePotato]

I am sorta new to the photon and i would like a way for my photon to send serial messages to the due, and for the due to control the computer.

I'll hand you this one:

Spark (3.3v) to Arduino (5v) Serial Communication

This is in reference to another thread, but I got a Spark talking via serial to my Arduino Uno using a logic level converter (I actually used one from eBay, but it works the same). The goal of this little test is to see if I could write from the Spark to the Arduino and listen for any serial data that the Arduino might generate. It’s pretty simple and straightforward. Since my test Arduino is an Uno, I’m limited to SoftwareSerial, so I had to scale down the baud rate. I will eventually tap t…

For more topics on the same, give the forum search function a try, it really does work "Arduino serial" seems to give quite a few hits.
