(I'M CONFUSED) Soldering Servos & LEDs To Arduino For Cosplay

As it will. Mechanical, not adhesive connections are where it's at. Then add adhesives anyway, like hot glue (not the little crafty kind, the hardware store kind) on top.

That's not good. Why not?

No biggie. Remember what I said about a REAL glue gun? Soldering not required if you use quality Dupont connectors...QUALITY Dupont connectors. Silicone jacket is best. Not the cheap starter kit crap. Check out your local RC Hobby shop, never mind 9V smoke alarm batteries and wimpy wires. Spend the few bucks to save you the money you'll otherwise be spending on Tylenol.

Can you please post your code using code tags and a schematic with all parts, connections, power source and such? The devil is in the details.
