I visualized data from an Ultrasonic Distance Sensor. Video1 Video2.
The diameters of the ripple like colorful ellipses become larger according to the distance that the ultrasonic sensor detects. I referred to this site.

We made a small “Rube Goldberg Machine” using a toy bug as an input, a photo cell as a sensor, a servo motor as an actuator. We also adopted a ball, a balloon and a needle for this device.

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 .

I made heartbeat using pulse-width modulation(PWM) with three LEDs; two red leds and a green led. I adjusted the parameter so that leds look like real heartbeat.Video

I made this animation inspired by a piano piece “Hibari” played by Ryuichi Sakamoto. In the music, you hear the repetition of a small phrase and subtle use of dissonance and that make the piece distinguished. In this animation, I adopted pendulum waves as an analogy for the music. Harmonic oscillations in the animation correspond to the harmony in the music and the discords of the waves correlate to the dissonance in the sound.
The note above shows how I calculated the angles of each pendulum. I also referred to the site below to determine the lengths of the strings.
