Day 16 oct 19

Here is the code for the el nino hw
#include<stdio.h>
#include<math.h>
#define FILENAME "ENS01.txt"
#define MAX_SIZE 1000
int main(void)
{
int k=0, year[MAX_SIZE], qtr[MAX_SIZE], max_k=0,nor_k=0,min_k;
double index[MAX_SIZE];
FILE *enso;
//READ SENSOR DATA FILE
enso = fopen(FILENAME,"r");
if(enso==NULL)
printf("Error opening input file. \n");
else
{
while(fscanf(enso,"%d %d %lf",
year+k,qtr+k,index+k)==3)
{
if(*(index+k)>*(index+max_k))
max_k=k;
if(*(index+k)<*(index+min_k))
min_k=k;
if(fabs(*(index+nor_k))> fabs(*(index+k)))
nor_k=k;
k++;
}
}
//print data for max el nion condition
printf("Maximun EL Nino Conditions in Data File \n");
printf("Year: %d, Quarter: %d \n",
*(year+max_k),*(qtr+max_k));
printf("EL Nino Conditions closest to normal in Data File \n");
printf("Year: %d, Quarter: %d \n\n",
*(year+nor_k),*(qtr+nor_k));
//Printout all
printf("Maximun La Nina Conditions in Data File \n");
printf("Year: %d, Quarter: %d \n",
*(year+min_k),*(qtr+min_k));
for(int i=0;i<k;i++)
printf("Year: %d, Quarter: %d, ENSO Index %.1f \n",
*(year+i),*(qtr+i),*(index+i));
//close file
fclose(enso);
return 0;

}




And here is a screenshot of the program running, it shows max El nino and la nina conditions, quarters closest to zero and all El nino data



For the lab we had to control the motor with serial commands here's the code
int M1_Left = 6; //Motor Input 1
int M1_Right = 5;
int M2_Left = 10;
int M2_Right = 9;
boolean inPin1 = LOW;
  boolean inPin2 = HIGH;
  boolean inPin5 = LOW;
  boolean inPin6 = HIGH;
char data;
//Motor Input 2
int val = 0;
void setup()
{
  Serial.begin(9600);
  pinMode(M1_Left, OUTPUT);
  pinMode(M1_Right , OUTPUT);
  pinMode(M2_Right, OUTPUT);
  pinMode(M2_Left, OUTPUT);
  //
  void turn(int direction);
}
void loop() {
//  val = analogRead(A0);
//
//  val = map(val, 0, 1023, -100, 100);
//  if (val < -3)
//  {
//    turn (1);
//    delay(-val); //1 sg
//    stop();
//    delay(20);
//  }
//  else if (val > 3)
//  {
//    turn (2);
//    delay(val); //1 sg
//    stop();
//    delay(20);
//  }
//  else
//    stop();
//}

  while (Serial.available() > 0)
  {
    data = Serial.read();


  if (data == '1')
    {
   
 
     forward();
     Serial.println("FORWARD");

   

    }
  if (data== '2' )
  {
    reverse();
    Serial.println("REVERSE");
  }
   
if (data=='4')
{
  Serial.println("speedUP");
  speedup(val+2);


}



   if (data=='5')
   {
    speeddown(val+2);
    Serial.println("speeddown");
 
   }

     if  (data == '0')
    {
      stop();
      Serial.println(" STOP");
      val==0;
    }
if(val>100|val<-100)
val=0;

//    if (data=='2')
//    {
//        turn (2);
//    delay(val); //1 sg
//    stop();
//    delay(20);
//    Serial.println("REVERSE");
//    }






}
}
void turn(int direction)
{
  boolean inPin1 = LOW;
  boolean inPin2 = HIGH;
  boolean inPin5 = LOW;
  boolean inPin6 = HIGH;
  if (direction == 1) {
    inPin1 = HIGH;
    inPin2 = LOW;
    inPin5 = HIGH;
    inPin6 = LOW;
  }

  digitalWrite(M1_Left, inPin1);
  digitalWrite(M1_Right , inPin2);
  digitalWrite(M2_Left, inPin5);
  digitalWrite(M2_Right , inPin6);
}
void stop()
{
  digitalWrite(M1_Left, LOW);
  digitalWrite(M1_Right , LOW);
  digitalWrite(M2_Left, LOW);
  digitalWrite(M2_Right, LOW);
}
void forward()
{
  digitalWrite(M1_Left,HIGH);
  digitalWrite(M1_Right,LOW);
   digitalWrite(M2_Left, HIGH);
  digitalWrite(M2_Right, LOW);

}
void reverse()
{
   digitalWrite(M1_Left,LOW);
  digitalWrite(M1_Right,HIGH);
   digitalWrite(M2_Left, LOW);
  digitalWrite(M2_Right, HIGH);

}

void speedup(int val)
{

    forward();
    delay(val); //1 sg
    stop();
    delay(20);
}
void speeddown(int val)
{

    reverse();
    delay(val); //1 sg
    stop();
    delay(20);
}

Here's a link of the motor running

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; } ...
