Hey everyone! I'm sort of sketching out the ideas for a more complicated, long term project, and I had a few questions on this end so as to hammer out some details.
At the moment, I'm looking to combine several elements of a few more simple projects floating around the internet, to make something more complex.
Ideally, I'd like to make something with two sets of ultrasonic and pir sensors, with matching oled displays for each of bitmaps of eyes (looking left, right, and center), which will follow an object based relative to the 'head', then as an extension of that, I'd like to attach two servo or stepper motors (for pan and tilt), which may additionally be triggered as the limits of the respective sensors are reached.
This is just the beginning steps, though.... Eventually, I would like to make an arm, then perhaps legs or something for mobility, etc...
Eventually, I would more than likely use something larger/more powerful to control everything, of course, but my current line of questioning is... is there a way to communicate between more than two Arduinos at a time, so as to have multiple components executing something more complex? Or, if not, how would I go about communicating these separate actions, and with what as an intermediary? I've compared what pins I would need for each sensor (and two motors, not even taking into consideration any more), and I could easily execute each part in separate pieces simply using Uno's, but as the project grows I wouldn't want to corner myself, and there's no Arduinos with enough pins for what I need (or anything else, for that matter). But if there are better ways to approach this that I may be overlooking, I'm certainly open to those as well. Thanks!
