After a year of acquiring new gear for my controller cabinet and a LOT of troubleshooting, I finally got this beast running! A huge thanks to Nick, Sean and everyone else on the forum who helped me get my basement intersection to where it is now!
The purpose of the yellow arrow and light is redundant, yes, but it will become a flashing yellow arrow once I get the programming changed!
Also one side of my flasher burned out so that's why only some lights are flashing red during the initial startup.
Enjoy and feel free to ask any questions or if you'd like to see some custom phasing and crosswalk sounds!

UPDATE: Thanks for all the views and following my channel! The setup has definitely evolved since this video and I always try to keep it interesting for my viewers!
