What I want to do is allow Arduino A to send some constant value to Arduino B.

I sense something inherently wrong with my approach, but I cant figure out what it is.

So in the diagram below you will see Arduino A setting its Analog Pin 0 as OUTPUT and write a value 2 every 500ms. On Arduino B we have Analog Pin 0 set as INPUT to receive and print data to Serial. The GND pins of both Arduinos are also connectconnected.

When this setup is executed, Arduino B is constantly receiving data in the form of a 3 digit number: starting with 3XX. I am starting to believe this is voltage value?
