Day 6

For homework we had to make a program  that computes the great circle distance between two points in the Northern Hemisphere.

Here is the program that calculates the angle between two vectors
Here is the code for the distance and angle between two points, I could get the added North and South function added but could not get the West and East one to work

For lab we had to use the  PIR and CdS sensors to control the LED.
Here is the light sensor working with the LED and this link shows the LED in action

I tried to get the PIR lab to work but couldn't get the sensor to work I could only get the light to turn off when i disconected the PIR.

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; } ...
