Hi all! 
I am wanting to make and big paper pache dragons head and have the mouth move (servos) to a sound clip, and also have red leds and mini fog machine in his nostrils. I just bought a raspberry pi 3 b+, and a pi 4 and have been playing around with them for a few weeks to get a better understanding.
Could someone please point me in the right direction how to do it? Like what servo controller? I see adafruit sells sound boards which one would I need?
I figured I would get the parts I need then research and play around with them till I get the results I am looking for. It’s just abit overwhelming with all the items.
Thank you, Randy
