Hello. I am building a diorama inside of an old GE blockbuster vintage boombox. I would like to pulse the VU meter on and off (move the needle). I see that I can use an Arduino to put power through the VU meter. I need help with what the wires on the back are for. I am a complete novice when it comes to electronic wiring. I assume the red is power, the white is ground, and don't know what the blue is. Can anyone help?
This is from a GE Blockbuster 3-5259A vintage boombox.

Maybe these projects by Rod Elliott, might give you some inspiration about how to adapt an all-electronic-hardware meter circuit, into a new hardware+software meter circuit.

Also there is a discussion thread here on the Forum called PeppyMeter, which talks about an all-software meter circuit. It may give you additional ideas and inspiration.
