== About Me ==

My name is Huyen Truong, and I'm a junior in the field of Visual Arts, emphasis on computing (but I would like to soon change that to film) I chose the major because art and entertainment's been an interest for me all my life. I don't remember a time where I've stopped drawing or writing for an extended period of time. However, like with everything, I've moved on with the time; art isn't just about pen and paper anymore. I've done a lot of self-learned experiments in Photoshop, Illustrator, Final Cut, computer languages, etc. but I've learned that self-taught work is not enough. I had hoped to do more hands on work with this major in UCSD, but so far the courses required are mostly on theories, which to say I am a bit disappointed. However, when I do get classes that have lab work (i.e this course) I am very excited to learn, although I have never worked with electronics in depth or engineered anything. I hope to have fun in this course and learn new things.

== Final Project ==

For my project, I plan on making an abstract, trippy Etch-And-Sketch. Instead of regular black and white lines, the player will instead be controlling three sets of colorful circles. I will use two potentiometers and a push button. The potentiometer will work like the regular up/down, left/right nobes for the sketching part. The faster you turn the potentiometers, the bigger the circular shapes will get. The push button would reset the sketch and change the background. I have incorporated the processing program along with the Arduino, and my laptop will be the 'toy' itself.

== Midterm Project ==

Originally, I had intended to do an hourglass switch, but since then I've changed it to a bootlegged Operation instead. The point of the game is to get a *wired* object out from underneath a bunch of other wires, but do not let them touch. The wiring of the Operation works like a Frankenstein switch. The wires conduct electricity, so when touched together, it completes a circuit.
