What I wanted to learn, and why it interested me: I wanted to learn how to output sound and control my mouse through a arduino micro just because I've never done anything in those two fields. 

Final outcome: 

1. a data logger that types the amount of times the button is pressed. 

2. sound with varying pitches being played whenever the button is pressed, while moving the mouse around randomly.

Process and reflection: 

Before the project, I saw Tim's keyboard interaction during presentation and I thought that was something new and cool, so I wanted to learn how to do that. This was how I started exploring the process of making a button that counts itself as it is being pressed. It was confusing to wire the Arduino Micro since it was my first time using it. I learned that Arduino Uno cannot control mouse and keyboard no matter how we code it. 

Unexpectedly, figuring out the wiring and soldering connections was the hardest part, and the code was just copying and pasting from the example code. Therefore,  I started exploring something different and more fun. 

I thought combining sound and button would be fun since I kind of expect a sound when I press a button. I then connected the buzzer and made it make a sound whenever the button is pressed. I learned that passive buzzer changes pitch and active buzzer changes volumn. Later, to create more interaction, I made the mouse move when the sound is played, and continue pressing the button will make the sound play like a siren. 

I understood how to use more components through this project and realized that storytelling would make the interaction much more engaging.
