Making motion with a servomotor. This example demonstrates a servo motor controlled by analog input from a potentiometer powered by an Arduino. Information is first created by turning the potentiometer knob, and is then sent to and translated by the Arduino for output from the servomotor. Arduino uses Pulse Width Modulation (PWM) to pulse the information to the output to 'fake' a fluid motion, similar to film, where a series of images are displayed one after another to trick the human eye into seeing motion.

My second lab assignment in Physical Computing. Finally, the power worked (I forgot to connect my ground and power directly from the Arduino to the breadboard bus). Code will be posted on my blog.

A photoresistor is a variable resistor that resists less electricity with more light intensity. In this example, I place my thumb over the photoresistor to decrease the amount of light the photoresistor senses. The photoresistor communicates this information to the Arduino. The information is translated into a digital code. We can read this code using

meridithpingree.com The Yellow Star hangs from the ceiling, like a chandelier without lights. Each link has a motor and a motion sensor creating slow jarring movements. This outline of the amoeba-like shape changes as people move through the space. It can see itself move, triggering more movement, cool chain reactions and behavior patterns. It's something between an animal and a toy. Meridith Pingree Yellow Star 2007 has been exhibited at: Supreme Trading, Brooklyn, NY, The Soap Factory, Minneapolis, MN, Sarah Lawrence College, Bronxville, NY, Gallery Afrerro, Newark, NJ, Millersville University, Millersville, PA, BakerIE, Greenwich, CT bakerIE.org meridithpingree.com

This is the documentation of my first step from my midterm. My group and I are trying to imitate the behavior of the mouse, using a mat for the floor. We have 4 force sensors use as a analog and 2 force sensors s as digital. What you see here is the serial communication in Processing

A beautiful necklace, in the form of a celtic knotted triangle, pulsates with red LEDs, displaying the heart rate of the wearer in a shimmering wave effect. Geek gifts of love at their finest.

For the servo section of Tom Igoe's Intro To Physical Computing at ITP, I built a motorized locker door out of Legos. My Arduino microprocessor is taped to the locker wall, just out of site, and a potentiometer is wired through to where the lock would normally be. From here it'd be pretty easy to program an actual combination lock using either the potentiometer or an analog or digital sensor. Try it.
