This is a mini test for my final project. the LEDs emit color onto a painted canvas. The canvas then indicates color by responding to a specific portion of the light spectrum.

int ledPin12 = 12; // Green LED connected to digital pin 12
int ledPin11 = 11; // Yellow LED connected to digital pin 11
int ledPin10 = 10; // Red LED connected to digital pin 10
int ledPin9 = 9; // Blue LED connected to digital pin 9

void setup() // run once, when the sketch starts
{
pinMode(ledPin12, OUTPUT); // sets the digital pin as output
pinMode(ledPin11, OUTPUT); // sets the digital pin as output
pinMode(ledPin10, OUTPUT); // sets the digital pin as output
pinMode(ledPin9, OUTPUT); // sets the digital pin as output
}

1. Critical assessment on information produced

   After you hand in your essays, I will give both grades and feedback.

2. (systems) The signal that is looped back to control a system within itself.
3. The high-pitched howling noise heard when there’s a loop between a microphone and a speaker.

This week we will be looking at a few digital and analog sensors, and time permitting, begin to look at other types of motors and motor control. This assignment will span a couple weeks and will culminate the precursor assignments.

Problem:

Create a “feedback loop” driven system utilizing sensor(s) + motor(s) of your choice, systems should be either biotopic or sociotopic systems and situate within some spatial context.

In today’s class we will be learning how to use a digital output to turn on and off a higher voltage/higher current load. Logically not any different than the LEDs you have been using, these circuits and parts will enable you to control the power of any electronic/electrical device around you.

Using the input method of your choice control a higher voltage device, either a 9-12volt element like a low voltage light fixture (commonly 12volts) or a line voltage device such as an incandescent light or your countertop coffeemaker. Create a system (input/ouput) that has some meaning and value to your everyday life. Consider revisiting the last assignment, replacing the LEDs with higher output lights for maximum impact.

Please exercise additional precautions and take your time as you build your project. Line voltage (110/120v) stings a bit more than the 5-9volts you’ve been using!!!!

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.

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
