Building a Pinewood Derby Timer: Wiring in the displays

Now that I have the displays mounted on the pinewood derby timer, it was time to wire them in. I still don’t have lights or sensors in yet, but I thought I could just hook up the displays for now. It seemed to work well!

I am using the schematics per the https://www.dfgtec.com/ website. Fortunately, the creator of the schematics, David Gadberry was kind enough to give it a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License, so guys like me can tinker with it!

Linux – keep it simple.
