Day 7

For lab we had to connect a speaker to the arduino, and modify the code to play a song.
Here's my code for that.

//Specify digital pin on the Arduino that the positive lead of the speaker is

int speakerPin = 9;
const int POT=0;
int val = 0;
void setup()
{
   Serial.begin(9600); //Start Serial Communication
}

//close setup
void loop() {
 /*Tone needs 2 arguments, but can take three
 1) Pin#
 2) Frequency - this is in hertz (cycles per second) which determines the
pitch of the noise made
 3) Duration - how long the tone plays
 */
  val = analogRead(POT);
  if (val<=139)
  {
 tone(speakerPin, 1000, 500);
 delay(1000);
}

if (val<=147 && val>=139)
  {
   tone(speakerPin, 150,500);
 delay(1000);
  }
 
if (val>=147&&val<=153)
{
 
 tone(speakerPin,400,500);
 delay(1000);
}

if (val>=154)
{
 
 tone(speakerPin,200,500);
 delay(1000);
}
Serial.println(val); //Print it to the serial port
 delay(500);
}

For homework we had to write a program that simulats rolling dice heres a screenshot of my code working

For this homework I could only get the dice program running I could not get the computing factorial program to run.

For the lab i had to write a program that causes an LED to change color depending on the temperature Here's the code //Potentiometer Reading Program const int POT=0; //Pot on analog pin 0 int val = 0; //variable to hold the analog reading from the POT const int BLED=9; //Blue LED on Pin 9 const int GLED=10; //Green LED on Pin 10 const int RLED=11; //Red LED on Pin 11 int ledMode = 0; //Cycle between LED states void setup() {  Serial.begin(9600); //Start Serial Communication  pinMode (BLED, OUTPUT); //Set Blue LED as Output  pinMode (GLED, OUTPUT); //Set Green LED as Output  pinMode (RLED, OUTPUT); //Set Red LED as Output } void loop() {  val = analogRead(POT); //Read one value from the POT  if (val <= 139)  { digitalWrite(BLED,HIGH); digitalWrite(GLED,LOW); digitalWrite(RLED,LOW);  } if (val<=147 && val>=139) {   digitalWrite(GLED,HIGH);   digitalWrite(BLED,LOW);   digitalWrite(RLED,...

For homework we had to modify the hand recognition code to read the knowns from a data file, create an array of unknowns from user input, point to the known value with the smallest difference, and print it all out. Here's the code #include <iostream> #include <cmath> #include <fstream> //#define FILENAME "known.txt" using namespace std; int main(void) { double known[5]; ifstream myfile ("known.txt");   if (myfile.is_open())   {     int k;     for(k=0;k<=4;k++) { myfile>>known[k]; }     myfile.close();   } //Declare and initialize variables. //double unknown[5]={5.4,7.2,7.9,7.4,5.1}; double unknown[5]; //double known[5]={6.2,7.0,8.0,7.4,5.8}; cout<<"enter 5 unknown values"<<endl; int k; for(k=0;k<=4;k++) { cin>>unknown[k]; } double distance(double hand_1[5],double hand_2[5]); double comp(double hand_1[5],double hand_2[5]); // Compute and print ...

For the homework I had to create a quick sort function, and then use a quicksort function in a linked list. Here's a screenshot of both parts of the homework: Just the quick list part #include <stdio.h> #include <stdlib.h> //void quicksort(int[], int, int); //int partition( int[], int, int); int partition(int a[], int p, int r) { int i,j, pivot, temp; pivot = a[p]; i = p; j = r; while(1) { while(a[i] < pivot && a[i] != pivot) i++; while(a[j] > pivot && a[j] != pivot) j--; if (i <j) { temp = a[i]; a[i] = a[j]; a[j] = temp; } else { return j; } } } void quicksort(int a[], int p, int r) { if (p < r) { int q; q = partition(a, p ,r); quicksort(a,p,q); quicksort(a, q+1, r); } } int main(void) { struct sort; int a[]= {25, 52, 37, 63, 14, 17, 8, 6}; int i; quicksort( a, 0, 7); printf("Sorted array is: "); for(i=0; i<8; ++i) printf(" %d", a[i]); return 0; } ...
