Hello everyone

If there's anyone who knows what is the problem with this, I really appreciate it.......


I built my lightsaber with cheapo soundboard like 1 week ago, but somehow I burnt the board with my soldering tool.

So, I bought a 2015 bladebuilder Obi-wan version, and got another board from that.

I just follow the guide from the forum,

and it worked before. But I don't understand any reason why it is not working right now.

With this board, the LED turns on when I wired transistor and the positive of the board, but it's working inversely (when the switch is on, LED turns off, but blink with Flash on Clash / the switch is off, LED turns on)

and with the negative, it's not working at all.


Is there anyone who know why, Please give some advice for me.

I'm holding this board like 1 hour, but I can't find any problems with wiring other part like batters, speaker, etc.
