while this project is currently shelved as it were, I have been having the urge to get at least a working prototype up and running. You know, just to see if it works.
Having a self diagnosed inability to knock up hardware has always stifled my projects; they really take off once I have something to code and program, but getting there? Jesus!
I found a small sheet of perfboard in my cupboard today; not my usual stuff I get with all individual holes, the stuff with tracks along it. Didn't even know I had it!
This has given me an idea.
Using this I can great the plane for my arduinos to plug into and link all the i2c pins together. A 4pin head attached at one end would allow for the master arduino to be connected simply, then a series of female headers will be used to attach the pro micro boards the the plane. Tracks could be cut to allow other pins to be broken off the headers, and header pins removed to stop any other arduino pin being connected to the i2c lines.
I need to find some female header pins but when I do I will give it a go!
