Hello everyone. my name is Jose Antonio and I am from Barcelona Spain, I have long wanted to make a ghostbuster costume. I have everything, and the proton pack I have printed it in 3d and the wand is a Hasbro spengle neutrona wand.now I have a problem, wanting to connect an amplifier in the proton pack I had to make a shortcircuit and the wand does not sound. I hope to find in you the necessary help to fix the damage.
best regads.
Jose
Hola José!
Probably would be best to ask about it in the Proton Packs section of the Equipment sub-forum.
Welcome aboard and best of luck!
Welcome aboard, Jose! 
Hello and thanks for your welcome.
I’m working with this tutorial:
https://github.com/gpstar81/haslab-proton-pack
bought three Elegoo nano arduinos and downloaded all the libraries, but I can’t get anything to work, everything stays off.
I have looked at the schematic countless times and everything is correct, but I can’t get it to work with any of the boards.
Any suggestion?
Hello and welcome
