Before i get too far into the design phase of a project i have in mind, is there a way to connect arduinos in a non-master/slave manner to pass a few different combinations of HIGH/LOW (say 5) or 'information' both ways using digital pins? Perhaps some library i don't know about?
Each of these modules should be identical and be able to connect on any face to any other module. I've included a crude image of what I would like to accomplish.
I've already determined that i can solder to these neodymium magnets without loss of magnetic properties by having the little magnets attached to a stronger magnet during the soldering process. Magnet to magnet connection shows only a very tiny resistance.
If it can't be accomplished, i will need to abandon the project and look for some other means to make my project. Thanks in advance!
