I don’t know where exactly the idea of a spinning doll came from, but my guess is from those jewelry boxes with the spinning ballerina and the music.
My project was extremely simple this time, I accidentally used a servo instead of a DC motor. Though, if I spent time fixing it I’m sure that I could make it work just as well with a DC motor.
The doll I bought from Daiso. I made the skirt (poorly) using extra fabric and hot glue. Below is the coding:
I used an online example and tweaked it in order to fit my continuous servo. The original code would make it turn 180 back and forth.
Here is a picture of the final product:
