+### About Actuator
+
+In general, an actuator is a device or mechanism within a control system that receives commands and generates force or motion based on those commands. In other words, it's a device that converts one form of energy into another.　For example, motors that convert electrical signals into mechanical motion.

+Furthermore, the definition at the Fabricademy includes Visual (LED) and Sound (Speaker).

+### Inspiration

After taking the class, I first thought that Fabric Speaker was interesting. I've used a variety of speakers from large to small, and I've also used them at Fabrication works. However, when I saw the Fabric Speakers, I started thinking again about the principle behind how sound comes from speakers.

I've built the ATtiny44 board several times at FabAcademy and used it in my [Final Project](https://fabacademy.org/2019/labs/kamakura/students/kae-nagano/projects/final-project/#bom-bill-of-materials). This time I didn't have an ATtiny microcontroller on hand, so I decided to use Adafruit's Gemma, although it's old product.
The Gemma is a microcomputer board that uses Attiny85 and can sew. It also has a Lipo Battery connector.
