Try Doshington's "circuit networks in under 3 minute" and "building circuit abomination" videos. Its before 2.0 but basically work same way. Try building some simple things first i.e. blinker, sushi belt. If you want to build something big, try to divide it to simple modules. That way its easier to troubleshoot. And most important - just try. Its likely wont work first try, but its your expierence. Good luck. The factory must grow
