We're working through the electronics for the Iron Man helmet and chest piece, and the Arduino Nano is the brain for most of it.
The CrashWorks board pre-wires every pin on the Nano out to a labeled jack along the edge of the board. Instead of soldering a wire to each pin, we plug a connector into the jack we want, and that pin is live. Each jack has its own dedicated purpose, which makes troubleshooting later way easier too.
That single design choice took the wiring step from "dad solders for an hour" to "Evan and I plug things in together," which is the whole point of doing this build the way we do.
The big takeaway for us is that a little bit of research and the right hardware choice is what lets my son actually do the build with me instead of watching, and that's worth more than saving the few bucks on a bare Nano.
Have you done any wiring like this on a project? How did it go?
