1. ## Free Fall

Hello, we're doing a lab where this is our task:

We have an Arduino Esplora Board and we are going to drop it so far. The goal of the lab is to have a print statement output : "Ouch! I fell %lf meters in %lf seconds"...

Here are the steps:

// Step 1 - print statement saying I'm waiting with dots.
// -- Dots depend on number of lines you're reading from esplora. "Every 10 lines"
// -- Tolerance - when acelleration is constant.

// Step 2 - When you drop it, esplora will accelerate, will then print the "!".
// -- "!" prints based on number of lines you read, you will print based off of timing you read.
// -- fixed variable , print a "." or "!" every 200 miliseconds.

Here's sample output:

Here's the code I have so far:
Code:
```#DEFINE grav 9.8
#include <stdio.h>
#include <math.h>
#define TRUE 1

double freeFall(double x, double y, double z);
int seconds(int tee);

int main(void) {
int t;
int count = 0;
double ax, ay, az;
while (TRUE)
{

scanf("%d,%lf,%lf,%lf", &t, &ax, &ay, &az);

printf("Echoing output: %d, %lf, %lf, %lf\n", t, ax, ay, az);

if(count > 0)
{
printf("\nOkay, I'm now receiving data");
int count = count + 1;
}

printf("I'm waiting ");

for(int i = 0; i < 10; i++)
{
printf(".");
}

}

printf("Ouch! I fell %d meters in %d seconds it was: %lf\n",  seconds(t), mag(ax,ay,az));

return 0;
}

/* Put your functions here */

double freeFall(double x, double y, double z)
{
double accel = ((x*x)+(y*y)+(z*z));
double accel2 = sqrt(accel);
return accel2;

int seconds(int tee)
{
int seconds = tee/1000%60; // 1000 ms in 1 second.
return seconds;
}

}```
I'm a little lost now. Any ideas?

2. #DEFINE is not #define I think, and generally constants are in all caps.
The function definition for seconds is inside freeFall

mag is undefined.

int count is declared twice.
