Hey all, I'm pretty new to Arduino and all that but I've been searching online for a while now and can't find what I am looking for so I'm gonna ask here if it exists.
What I'm trying to do is actively block a connection between something on a different grid than the arduino but if I connect a transistor between them the arduino has to be constantly plugged in for it to work and allow the connection. What I need is sort of an inverted transistor where it always allows the connection until the gate pin is hit with a high signal and then the transistor cuts off the other grid's connection. But I can't seem to find a way to do this.
If you want schematics or something I can make those easily but I don't find it quite necessary so I'm not uploading it with this post. Just ask if you need one.
Thanks in advance to whoever can help! I hope there is a way to fix this.
