Turning on a sound board and led with a DPDT switch
So I finally got around to wiring up my first saber last night and everything went pretty smooth for the most part. My only problems were with the relay I was trying to use. I couldn't get it to work properly for the life of me, so I ended up ditching that idea. Instead I just wired my main led off of the sound board. Everything lights up but I'm using a 2010 Obi Wan Hasbro board so my P4 isn't nearly as bright as it should be, seeing as it's only running at about 30ma.
My question is, I was thinking that I could use my AV switch to turn on the sound board as well as the P4, since it's a DPDT switch. Now my problem is I have no idea how I would hook up the P4 to achieve this. I've currently got the sound board hooked up to the NO1 and C1 posts. Should I hook up the P4 to the NO2 and C2 posts? And where exactly should I hook the P4 into the battery pack at?
