Day_4

Comments: The programming homework was pretty straight forward, well at least I think it is anyway. What's killer was the arduino homework, since I have to implement the debounce, which I have yet to figure out. I managed to change the color of the RGB to the desired color, but haven't managed to get the color to change on the button pushes. I will probably ask David to help me figure out how to debounce the button to get the RGB to work.
2. Give the value of a after the following set of statements is executed.
int a = 750; ...
if (a>0) (which it is)
 if (a >= 1000) (It's not)
a = 0;
else if (a < 500) a *= 2;(It's not)
 else a *= 10; [a*10 =a], since a =750, [a=750*10]
else a += 3; (not true)
answer 7,500

Comment: I had a lot of trouble understanding how to code works for the homework, I couldn't finish all of the modifications without getting an error. So I only finished the first three modifications, which took me a long time to develop. For this lab I initially had trouble getting the speaker to change the pitch according the the change in temperature. Turns out I had an extra if statement in my program and that resolved the problem. I spent about 4 hours debugging before I found the extra if statement. Also, I used a potomieter because the speaker would make the lcd screen go crazy since without the pot there was no resistance. /* This program determines the locations of peaks in an */ /* grid of elevation data. */ #include <stdio.h> #define N 25 #define FILENAME "grid1.txt" int main(void) { /* Declare variables. */ int nrows, ncols, i, j,count=0,count_2=0; double elevation[N][N]; double valleys[N][N]; FILE *grid; /* Read information from a data fi...

I couldn't figure out how to get the program to work initially, so I called Sam and he told me that he figured out to replace the underscore with a period for the f_fingertip. The program worked after and I took some time to figure out how to print the count and percentage of each category. Overall the modifications weren't too difficult once you figured out how to print the counts. /* Finger print program*/ /* It then references a function to compute the overall category.*/ #include <stdio.h> int k,l,j,i=0; double pow,pol,poa,arch_2,whorls_2,loop_2;//whorls_2 is equal to i becuase it must be double to calc percentage //pow is percentage of whorls /* Define a structure for the fingerprint information. */ /* The order for fingertips is right hand, thumb to pinky, */ /* and left hand, thumb to pinky. The codes are L for loops, */ /* W for whorls, and A for arches. */ struct fingerprint { int ID_number; double overall_category; char fingertip[10]; }; int ma...
