Final Project

Final Project – Piano Player

Processing was used to see the motions as the piano is played. Since it is the holiday season, I chose a Christmas carol, Jingle Bell, for the song. Using Jingle Bell’s music note, press the right note on the piano and a motion is played telling a story. The motion does not play if you press the wrong note.

Midterm Project

kooh125 — Thu, 20 Dec 2012 08:34:36 +0000

I made a piano player using processing and iPhone, something that is friendly and easy to play. I chose iPhone so that people can play by tapping on the screen rather than clicking a mouse and a keyboard.

OpenFramworks

kooh125 — Thu, 06 Dec 2012 15:14:35 +0000

When I used openFrameworks, it was different from Processing because openFrameWorks is similar to c++ and is divided into draw, update and setup, whereas Processing is closer to Java and uses draw and setup. Because the language used in openFrameworks was different, there were many errors at first. I had to find everything which took me a long time but overall it was a good experience.

Week9 / Realtime Data Visualization

I made Realtime Data visualization using an arduino, processing and sensor input. I try to tested flex sensor,force sensitive resistor, photocell and tilt sensor. Finally, I used force sensitive resistor and other sensors are sensitive so did not work very well.

- Instruction -

Circle automatically be drawn center of stage.when you pressed force sensitive resistor, circle shape draw little bigger and when mouse is clicked, it will reset to new start.

Week8 / Rube Goldberg Machine

I made a small Rube Goldberg machine using pressure sensor and servo motor. I needed something that had movement so I bought two kinds of DC Motor and also a Motor shield kit. But it was still not easy to do and I changed to servo motor. For pressure sensor, I just wanted to try it and chose two kinds of sensor to play with.

1. Press pressure sensor

2. When the servo motor pushes the blue car forward, the blue toy starts to shake its arms and feet

3. Small blue car knocks down the wood piece

Pulse Sensor

We used a pulse sensor Julie bought at Maker Fair. Pulse sensor consists of a led and a photocell as a detector. You can see how a pulse sensor works from this site.
We applied these sample codes. We downloaded “P_PulseSensor_06.zip” and PulseSensorAmpd_Arduino_01.zip .

Week7 – animal

kooh125 — Tue, 16 Oct 2012 04:02:33 +0000

I made an animal using Arduino and Arduino Uno for the first time. When I got the assignment, I had no idea what to make. But after seeing other classmates’ posts, I figured it out and made a crocodile. Actually, I saw crocodile character on the webpage so I used this character on my project. I used 12 LED (3 red and 9 green) and I tried to connect ground, 9, 11 and 12. For next time, I would like to make one using a speaker.

Parallel and Series Circuit (Github)

Github Text

I’m excited to make a something with LED but I’m still confused about it.
I didn’t know where to put the wires correctly that I burnt two of the bulbs.
Also, I don’t know if my calculations for voltage, resistance, and current is right.

Assignment 3 + 4 – Music Player

kooh125 — Tue, 02 Oct 2012 03:01:08 +0000

for last week, my assignment3(music player) was did’t work correctly and Liza told me to finish it for assignment4 (using one library and class).
I’m using a minim and 2 classes to make music player!! Here is the link to the code on github.

Instruction
- Choose Song and Artist (same as iPhone player)
1. Christina Aguilera – What A Girl Want
2. Bruno Mars – It Will Rain
3. Carly Rae Jepsen – Call Me Maybe
- Play / Stop : Control music to play and stop
- Playlists : Go back to main page
