From your link:

  • Admin Features : For administrative purposes, the system may include an additional level of security through a keypad, enabling authorized personnel to access attendance records or add new users.

I doubt this works with 10 users...

else if (id == 6)
{
  eepLoc = 840;
  user = user5++;
}
else if (id == 7)
{
  eepLoc = 1050;
  user = user7++;
}
else if (id == 8)
{
  eepLoc = 1260;
  user = user8++;
}
else if (id == 9)
{
  eepLoc = 1470;
  user = user9++;
}
else if (id == 10)
{
  eepLoc = 1680;
  user = user8++;
}

Can you explain why it won't? I'm kind of confused at the moment

4

Although I tried it. It did

5

Is the code you posted the code you got, or the code after you started trying to make it work for sixty users?

Please say, or post the original unmodified sketch.

In any case, what you might wanna learn about is

arduino functions

and

arduino array variables

both those search terms will turn up official reasonably good introductions to those key programming concepts.

This says: "if ID is 6, increase 5"... why 5 and not increase "6"?

copy/paste/edit/fail.

It did not work.

But you could not possibly tested it very well.

Without seeing any more of your code than the below, it is obvious that you have typographical error, or the strangest code ever built:

else if(id == 5)
{
eepLoc=0;
user=user5++;
}
else if(id == 6)
{
eepLoc=840;
user=user5++;  // <----- right here, see what you missed?
}
else if(id == 7)
{
eepLoc=1050;
user=user7++;
}
else if(id == 8)
{
eepLoc=1260;
user=user8++;
}

That's one of the many disadvantages to growing your sketch by copy/paste/editing working blocks of code.

This is the code that I got.

I only changed added some comments, change the delays, and modified the code of the LCD in that code

12

Okay, I'll change that

That made me confused as well, thinking there's a reason behind that mistake or what

13 
else if(id == 10)
{
eepLoc=1680;
user=user10++;
}

It's only 10 users in the code that I copy pasted from Fingerprint Based Biometric Attendance System using Arduino - SovanHax

else if(id == 11) // 
{
eepLoc=1890;
user=user11++;
}

I want it to have 11 users and more (up to 50). Am I doing the right thing? Do I just add 210 to the eepLoc, since the eepLoc started with 210?

14

You should show the new sketch you have after the changes you made.

You said you posted original unmodified code. did that code have this:

// user11,user12,user13,user14,user15,user16,user17,user18,user19,user20
// user21,user22,user23,user24,user25,user26,user27,user28,user29,user30
// user31,user32,user33,user34,user35,user36,user37,user38,user39,user40
// user41,user42,user44,user44,user45,user46,user47,user48,user49,user50

Did that code have those typos?

If not, please post the original unmodified code.

TBH that code is not very good, and it is not a good idea to use it to copy/edit/paste your way to 60 users.

Have you looked into functions and array variables in the context of Arduino programming?

I'll wait. :expressionless:

still going to

I made that actually but eventually turned it into comments since I'm not sure about it

19

I appreciate you for letting me know about it. I'm willing to learn about this

I only have a moment here, but a tip,is to start using the IDE Autoformat tool.

It will,put your code into into a standard format, with nice indentation and so forth that will make it pretty and much easier to read.

Try it now. You could edit the last post where you placed the original original code (THX!) after applying the Autoformat tool to it in the IDE, then just paste right over the code you posted, leaving the tick marks that make it appear as code I damaged.
