I'm trying to get it so that on the circuit can be optimized more, there is probably a lot of things that can be done to make is so that I need less DC power sources and get it all hooked up properly. I'm trying to get a transformer hooked up to this but whenever I do its just greyed out and doesn't do much of anything. My end goal for this project is to get this to produce DC-AC from a 555 timer. I'm pretty new to the electronics scene (high school hobbyist) so I don't really know too much on how all of this stuff works. Any insight and help would be greatly appreciated.
