Yes to the multiple boards. The dude happens with or without any hook ups. Is there a way to check if boards are damaged, cause the ones I used were not new. I have tried a number of Sketch's that comply and have uploaded before without issue . Now I get this dude error when I try them also. I also tried a different computer same issue. I took all Arduino files off computer and started over that did not work either. {uninstalled also}.I just made the lego bulldozer 3 x scaled up and have been trying for 3 weeks to solve this issue and get it running. I haven't run into any dude I couldn't get along with but I guess there is always the first one . got to keep pushing on, maybe I'll get lucky. This is My issue message
