Secondly, we added a blue row to our LEDs and now show the open/closed/groomed status for 16 trails. I tried to make it a little easier to see the different rows by putting the cardboard on top. Here's a quick guide, Red = Closed, Green = Open, Blue = Groomed. Only one light will illuminate for each trail. Next step would be to do this with a single RGB LED. Also to note what it is doing, I create a quick startup sequence that runs when I reset the Arduino. Then I click 2 buttons I created in the flash program to turn on trails 1-8 & 9-16.
