I’m in the process of remaking my “Doom Pumpkin” for Halloween as well. If connects to my HomeAssistant setup and has four 12v car horns, a speaker to play audio, LED’s for eyes, a big red arcade button for a nose, motion sensors in front and back to interact with kids (it tells them it farts fireballs if they walk behind it) and an anti theft mode where if it’s picked up the horns start going off. Press the button and a random sequence of horns will go off. It also will randomly set a horn off if it hasn’t been touched in a while. And when it senses someone in front it will taunt them to press the button. Since it’s built in to HomeAssistant I can set when certain functions work and for a couple days before Halloween it will be outside taunting the neighborhood during the day.
The first version was a couple horns powered by an arduino uno and would just randomly activate 2 horns in different ways. The new one added two more horns (one is a little beep beep forklift horn, the other is an oooogah horn) to go with the high tone and low tone car horn.
