Hello everybody
I'm trying to make my own lightsaber with sound using the Hasbro Luke Skywalker bladebuilders 2015 LB.
I wanted also to add a rechargable battery with a micro-usb so I don't have to change batteries every time.

In my configuration, my goal is to use 2 switch, one for just the led, for just practice and training. the second switch will instead power also the soundcard and everything else.

I did the following schematic, I don't know if it's correct, that's why I am here, and before proceed I would like to have all the possible advices from u experts
As a final note, i don't know what to do with the IN+ and IN- plugs in the microusb card....should I attach them somewhere?
