It's been a long time....

[tetters]

Taking a break from structures I went down another rabbit hole of mine...Arduino sketches and circuits.  Full disclosure;
...I have no idea what I am doing half the time and get a lot of instruction and help writing sketches, building circuits from online sources.  That said, I've been working on a circuit that will operate some grade crossing signals.  I'm almost there too.  I've been able to get the lights to flash at an appropriate rate however for some inexplicable reason they'll speed up a bit...maybe some wonky sensors or I need to fudge the code some more.  Either way, I'm amazed I got this far and got it to work at all. 

   

I have only one grade level crossing on my layout...granted it's also three tracks but adding some additional photo cells and two more lights for another set of crossbucks and I should be good to go.

I'll keep everyone posted on how this goes and when I'm ready to install this on my layout.
