How-To: Daisy Chain Arduinos via Serial

If you have a project that uses a bunch of Arduinos, how can you get them to communicate together? Scott Lawrence from The Geodesic Sphere shows us how to daisy chain multiple Arduinos together via their serial ports. He used this technique for his long-term Animatronic Avian project inspired by Disneyland’s Enchanted Tiki Room. [via Hack A Day]

  1. Wow Scott, nice work! I think I’m going to have to try this out tonight. This kind of thing (needing to communicate between a host server and multiple micros simultaneously) come up for me pretty often and this is much more elegant than my solutions. Cheers for sharing!

  2. Thanks! There will be more to come on this soon. I’m working on implementing the “network” protocol described in the post now. I have a preliminary test and it looks good so far!
