3D Printed Start Light Gantry w/ Race Coordinator & Arduino on Donnybrooke Motorsport Park Update

Just an update and wrapup of a project I started a while ago. A 3D printed start light gantry for Donnybrooke. Made with discreet LEDs and wired into the Arduino Mega I'm using with the track, connected to the PC via bluetooth and basically operated by Race Coordinator timing/scoring software. The software also has possibilities of setting up for "fuel" type races where you do "refueling" during a race, lap leader indicator LEDs if so desired andseveral other things that I'm not using. A start light gantry isn't required for racing in our club, but it is cool looking. So there you go. Hope someone gets something out of this project, like understanding that nothing works when the software is in DEMO mode! DOH!!
