Basics

• Project TitleRandom Poetry Generator
• ThemeCoding, Arduino, Creativity
• Submitted ByJennifer Leonard
• OrganizationThe Skills Library
• Brief DescriptionA random-poetry generator using an Arduino board and circuit based on the Snap Circuits "Snapino" set. Turn the crank on a generator, then pause, and random words appear on the computer screen to create a random poem. The faster you turn the crank, the more poetry you get.
  
  The program is pre-written, including an array of words for the random poetry, and participants can modify the program and array of words.

  Hand-cranked generator or motor (from another Snap Circuits or Thames & Kosmos set)
  Computer with Arduino software, as described in the Snapino set

• Random Poetry Generator (Arduino Sketch)

  // first set up some variables that will be used in the program
  // r will be a random number that the program selects
  // s will be the previous random number... just because we do not want to use the same number twice in a row
  // delay1 is used to tell the program how much to pause between each step
  // the other fields define the pins on the micro-controller board and define a sensor reading that will measure how much power you get from the generator
  // the sensor reading could also pick up a reading from other sensors, such as a light sensor or motion detector
   

  long r;
  long s;
  int SensorReading = 0;
  int delay1=200;
  int i=1;

  const int ledPin =  10;
  const int button = 9;   
  const int mysensor = A0;

  void setup(){
    Serial.begin(9600);

      pinMode(ledPin, OUTPUT);
      pinMode(mysensor,INPUT);   

    // if analog input pin 0 is unconnected, random analog
    // noise will cause the call to randomSeed() to generate
    // different seed numbers each time the sketch runs.
    // randomSeed() will then shuffle the random function.
   // or fill in a number to start the randomization, such as randomSeed(4)
    randomSeed(1);

  }

  void loop() {
    SensorReading = analogRead(mysensor); //Read the value of the A2 pin and assign that value to Val
   
    char* myPoemArray[]={
      "morning",
      "evening",
      "song",

  if (SensorReading<=300) {     
      digitalWrite(ledPin, HIGH);    //If the sensor meets the IF condition then turn on the LED

    // loop through this routine four times
    // choose a random number and then print that word number from the array of words
    // (unless it is a repeat of the previous word)

    int x = 1;
