I was always interested on how musical stuffed animals were made, so I decided to try it for myself 🙂
The successful goal of this project was to create a conducted system that would react to temperature. The reaction being different colors and songs for a certain temp. Once the stuffed animal is squeezed, a specific song would play determining if it is hot or cold.
Materials Needed:
Alligator Clips, a portable charger, USB cord, needle, thread, and a stuffed animal.
Instructions:
- We start off by connecting the parts together. The alligator clips are going to be connected to the speaker, once connected, clipping them in the order of GND to GND; power to VOUT, and signal to A0.
- Once that is done, connect the USB cord to the side of the Circuit Playground Express. The other end of the USB cord to the Portable Charger.
And that’s it for the building! One problem I had ran into was having to switch my battery source in the beginning because the coin cell battery was not powerful enough; until I was suggested to use a portable charger, which solved my problem 🙂
The coding for the Circuit Playground express was made on Make Code provided here. The intentions of this project was to create a code that would trigger a reaction to the Playground depending on the temperature. The initial temperature once turned on (the project) would play a specific song , being the Harry Potter Theme Song; once the temp rises to a certain temperature, it would play a different song along with a different ray of colorful lights.
Once that is done, you can put your physical project inside the stuffed animal, then stitch back up. Or you can also use velcro, which what I did. Then BOOM! You’re done! 🙂 Thank you
