I thought about using some industrial strength Velcro to keep everything secure, without that squishy-wobbly feeling that you can get from regular Velcro. Because this Velcro is so strong, I cut it into strips and made sure that the breadboards and Arduino mounts would never have complete contact between the Velcro. This would make it so the pieces could still be moved when needed.
Step 1: Arduino-plex 1.0
I needed a way to shift work to something new, without completely destroying the previous project. I also built this board when I only had 2 Arduinos, and now I will be ordering a 5th board shortly. Clearly, I needed to build a new board.
