Please, can someone help me with this sketch? Originally it was written for lcd display but I need it for
7 segment led, but it wont work.So pleeeease, what em i doing wrong?

What happens? What is the problem?

How can i post the sketch?

In code tags. Please read the post:

float sensorValuex = 0;  // assign a floating point value of "0" to a variable called "sensorValuex"
float sensorValuer = 0;  // assign a floating point value of "0" to a variable called "sensorValuer"
float slope;             // assign a floating point value of "0" to a variable called "slope"
int n = 0;               // assign an integer value of "0" to a variable called "n"
int cursorClmn = 0;      // assign an integer value of "0" to a variable called "cursorClmn" 
int numSamples = 0;      // assign an integer value of "0" to a variable called "numsamples"
float slopeTotals;       // assign an integer value of "0" to a variabel called "slopeTotals"
float slopeAve = 0;      // assign an integer value of "0" to a variable called "slopeAve"
int VDI = 0;             // assign an integer value of "0" to a variable called "VDI"

If your teacher told you you have to comment everything, this is not what she meant.

float slope;             // assign a floating point value of "0" to a variable called "slope"

It's a good job crt0 does what you forgot to do.

void loop()
{
first:

Uh - oh.

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html
then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

Thanks.. Tom.... :slight_smile:

The problem is that it wont print the forecast on display.

Was reading the how to use the forum post that hard?

Fixed it :wink:

Okay, to the code. Holy cow, that is the worst piece of code in times. Someone got the "use documentation"-note but missed every other note... Like:

int cursorClmn = 0;      // assign an integer value of "0" to a variable called "cursorClmn"

YESSS, we can see that! But what does it actually mean!

And the "don't use goto"-note. It's C++, use a function, please!

Okay, and then up to 7-segmenting.

  byte numDigits = 2;
  byte digitPins[] = {4, 5};
  byte segmentPins[] = {6, 7, 8, 9, 10, 11, 12, 13};
  sevseg.Begin(1,2,3,4,5,6,7,8,9,10,11,12,13);

  sevseg.PrintOutput();

Have you even read the Library help page? Declaring useful variables then not using them and calling Begin() with a bunch of random variables... Calling a non existing function in loop... Why?

OK
Thank You for advice (programming is not for me)
regard

We don't say that :wink: But you should not start with crap code like that. Starting with crap makes everything difficult :wink:

This "if" is not like the others.

if (VDI > 45, VDI < 65); {

It needs two changes if (VDI > 45 && VDI < 65) {
