As newbie, I encountered a problem, I don't know how to solve.
I use 3 ic's 2x 7404 and 1x 74LS08
During the routing these 3 IC are connected together by Vss and ground. But the ground isn't connected to the ground of the system. Also the Vss pins aren't connected to the powersupply, a 7805.
I assume I have to "tell" eagle to make these connections, but I can't figure it out how to do this.
Does someone know?
