I downloaded a program from http:// www.instuctables.com/id/LEGO-T-Intersection-LED-Traffic-Light/?amp_page=true
After a few hours typing into the Web Editor for ARDUINO Nana. I hit the verify button and all of these faults came up. There are 2 downloads from the sight. The first is for T intersection and the 2nd is for a Cross Intersection. Is it possible is any of you smarter guys or girls out the in webspace could download the Cross intersection Program install it then work out the several faults and fix them? Please let me know how you went.
I hope someone can help me.
