1st let me introduce myself - I am pretty new to the TI Launchpad boards, even thou I own 3 or 4, I've not really done much in the way of projects. I was given a MSP432 and I have a lot of ideas for that. But currently most of my projects are done with either an Arduino board, or one of the NodeMCU (ESP8266) boards or clone. So....My halloween project this year is based on the NodeMCU, a MP3 player, and a neopixel ring.
It checks the cheerlight lights color, changes the colors of the neopixels, plays spooky sounds, and is in a pumpkin head. Easy project to do.
