I just realized that I forgot to post the my post as I was to0 excited to enjoy my holiday. Last week we learned how to use hardware to mod Doom. I disassembled the mouse I brought from China. It was cheap yet firm. I really had a hard time when I tried to break it. The melting metal was also hard. I figured out how to get rid of the original metal with the help of Patrick. However, my addition of two wire failed apart once I back to home.
For the Arduino, I really had some problems. I was not able to catch up with the lecture and only able to make the blink work. Therefore, I could not make the left click mouse at a certain pace which was shown in class. 
For my final project, I have two approaches now. One is if I finally figure out how to use the Arduino to control, I will make one like Crypt of the NecroDancer, which the player can only move at beat. If I can not, I may make a game that is more about the environment and story rather than a level about killing monster. I probably will polish my Alice in wonderland and add more story into it.
