Is there something that you can get that you plug one end into your pc and the other end connects to appliances or whatever so that you can control them through your pc. Maybe just send power through a circut or something. For example, would there be a way to wire something where I could turn off my lights from my PC. Or turn on Christmas Lights hanging in my room that are just plugged into the wall when they are on now and unplugged when they’re not. Or set it up so there’s a little spring or something that cocks then fires or maybe an electromagnet that would open or close my door.
That would be so cool 
Anyone know of anything like this or a way to do this?
