// Controlling a servo position using a potentiometer (variable resistor) 

// by Michal Rinott <http://people.interaction-ivrea.it/m.rinott> 

#include <Servo.h> 

  Servo myservo;  // create servo object to control a servo 

  int potpin = 0;  // analog pin used to connect the potentiometer

int val;    // variable to read the value from the analog pin 

  void setup() 

{ 

  myservo.attach(9);  // attaches the servo on pin 9 to the servo object 

} 

  void loop() 

{ 

  val = analogRead(potpin);            // reads the value of the potentiometer (value between 0 and 1023) 

  val = map(val, 0, 1023, 0, 179);     // scale it to use it with the servo (value between 0 and 180) 

  myservo.write(val);                  // sets the servo position according to the scaled value 

  delay(15);                           // waits for the servo to get there 

} 

Knob

Control the position of a RC (hobby) servo motor with your Arduino and a potentiometer.

This example makes use of the Arduino servo library.

Circuit

Servo motors have three wires: power, ground, and signal. The power wire is typically red, and should be connected to the 5V pin on the Arduino board. The ground wire is typically black or brown and should be connected to a ground pin on the Arduino board. The signal pin is typically yellow or orange and should be connected to pin 9 on the Arduino board.

The potentiometer should be wired so that its two outer pins are connected to power (+5V) and ground, and its middle pin is connected to analog input 0 on the Arduino.

// This example code is in the public domain.

#include <Servo.h> 

  Servo myservo;  // create servo object to control a servo 

                // a maximum of eight servo objects can be created 

  int pos = 0;    // variable to store the servo position 

  void setup() 

{ 

  myservo.attach(9);  // attaches the servo on pin 9 to the servo object 

} 

    void loop() 

{ 

  for(pos = 0; pos < 180; pos += 1)  // goes from 0 degrees to 180 degrees 

  {                                  // in steps of 1 degree 

    myservo.write(pos);              // tell servo to go to position in variable 'pos' 

    delay(15);                       // waits 15ms for the servo to reach the position 

  } 

  for(pos = 180; pos>=1; pos-=1)     // goes from 180 degrees to 0 degrees 

  {                                

    myservo.write(pos);              // tell servo to go to position in variable 'pos' 

    delay(15);                       // waits 15ms for the servo to reach the position 

  } 

} 

Sweep

Sweeps the shaft of a RC servo motor back and forth across 180 degrees.

Circuit

Servo motors have three wires: power, ground, and signal. The power wire is typically red, and should be connected to the 5V pin on the Arduino board. The ground wire is typically black or brown and should be connected to a ground pin on the Arduino board. The signal pin is typically yellow, orange or white and should be connected to pin 9 on the Arduino board.

Project 2 Brief

Emotional Objects

Investigating Human Auto-Response

The human body is a complex system of surfaces and organs that can detect heat, light, sound, movement, and we respond to these stimuli, or inputs based upon a contextual map of our surroundings, and in some cases our emotional state. As well as this, emotional stimuli can also elicit a physical response that for many of us is uncontrollable, for example blushing. 

----------------------

Using the Arduino microprocessor you are asked to design an object which exhibits the human response characteristics to an input factor, based upon a specific human response to stimuli . You may choose one of the input response characteristics below or choose your own stimuli and response if you desire. 

Stimuli input= cold, heat, noise, light, movement, fright, embarrassment, physiological processes, proximity to others, tickling.

Designed attributes you should consider are

- A computer program for an Arduino microprocessor that is able to take this input and control an output device in a predetermined (by you) manner

- A sensor or sensors that are able to detect an input - An appropriate output device. - An electronic circuit to enable the above constructed on a Breadboard.

- A physical manifestation of your design that will contain the Arduino, breadboard and power supply. The design of the form is expected to be contextualised around your stimuli and response.

  Button

   Turns on and off a light emitting diode(LED) connected to digital  

 pin 13, when pressing a pushbutton attached to pin 2. 

     The circuit:

 * LED attached from pin 13 to ground 

 * pushbutton attached to pin 2 from +5V

 * 10K resistor attached to pin 2 from ground

   * Note: on most Arduinos there is already an LED on the board

 attached to pin 13.

// constants won't change. They're used here to

  Analog Input

 Demonstrates analog input by reading an analog sensor on analog pin 0 and

 turning on and off a light emitting diode(LED)  connected to digital pin 13. 

 The amount of time the LED will be on and off depends on

 the value obtained by analogRead(). 

   The circuit:

 * Potentiometer attached to analog input 0

 * center pin of the potentiometer to the analog pin

 * one side pin (either one) to ground

 * the other side pin to +5V

 * LED anode (long leg) attached to digital output 13

 * LED cathode (short leg) attached to ground

   * Note: because most Arduinos have a built-in LED attached 

 to pin 13 on the board, the LED is optional.
