Assignment 2

Detection

From Wikipedia, the free encyclopedia

“In general, detection is the extraction of information from any clear or clouded ambient or otherwise accessible stream of information without neither support from the sender nor synchronization to the sender.”

Considering the term detection, create an application that uses at least a few of your analog inputs to detect activity within a space. This could be the motion or passage of occupants, interior or exterior light levels, etc.. With the data you receive from your inputs, control some type of pulse width modulated output, such as dimming LED’s or controlling a servo motor. Design your system for a specific condition within crown hall and document the activity at an appropriate time for maximum efficacy.

assignment 1

in·di·cate (ĭn’dĭ-kāt‘)

tr.v., -cat·ed, -cat·ing, -cates.

1. To show the way to or the direction of; point out: an arrow indicating north; indicated the right road by nodding toward it.

2. To serve as a sign, symptom, or token of; signify: “The cracking and booming of the ice indicate a change of temperature” (Henry David Thoreau).

3. To suggest or demonstrate the necessity, expedience, or advisability of: The symptoms indicate immediate surgery.

4. To state or express briefly: indicated his wishes in a letter; indicating her approval with a nod.

Based on an architectural interpretation of the term above, develop an application for sequencing multiple led’s using the arduino. For this assignment you must utilize all 14 digital pins on the board, each pin can be either an input (switch) or an output (LED). Each output pin may have one or muliple LED’s. You will have to calculate the required resistance needed for each pin and utilize the correct resistor.

After completing the mockup take photos or video documentation of the project and post a description of the idea and implementation

Class introduction

An exploration of the technologies enabling interactive architecture through hands on demonstration and small scale design-build projects where students will deploy basic electronics and programmable computer control systems for physical architectural installations. To start, students will be introduced to the concept of play as it relates to design and interaction and begin establishing the vocabulary of this type of design development. Over the course of the semester a wide range of projects, with both artistic and pragmatic objectives, will be discussed. In tandem to the background knowledge students will be taught the basic electronics and introductory computer programming required to implement the technologies themselves. Hands on workshops will introduce students to computer controlled lighting and motor control for creating architectural conditions which can react to GPS tracking, computer-vision, and a range of environmental sensors. The objective of the class is to enable the students to work individually or in small groups to develop working prototypes of interactive architectural conditions. Wall, floor, ceiling, window, door, … As such the first half of the semester will include a series of assignments focused on specific technologies that should enable the students to work more freely on an area of personal interest for the final project.
