WHY IT IS COMING?

system · August 24, 2018, 12:57pm

ATTCHMENT is half code my project . During writing code I think to compile my code now to check whether I am writing code correctly or not.

But after compiling I got 2 errors . THAT ARE -------->1.expected initializer before 'void'[HIGHLIGHTING void loop()] 2.expected initializer before 'void'[HIGHLIGHTING void setup()}

WHY IT IS COMING?

HELP ME!!!!!!!!!!!!!!!!!!!!!!!!

Post all the code, post the exact error message.

Edit: Don't report sound advice to the moderators.

Danois90 · August 24, 2018, 1:13pm

Have not looked at the code, usually the error is related to a missing semicolon ";" or a missing library.

Check the </> code tags when posting your code.
I - for one - rarely read 'attached' code

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.

What model Arduino are you using?

Sorry i didn't know how to post code but next time i will do in same manner as shown.

And i am using ARDUINO UNO

You still need a semicolon, whatever processor you're using.

A semicolon missing.
This has already been mentioned.

Now it is working .......

THANKS!!!!!!!!!!

THANKS!!!!!!!!!!

How? Did you fix the "vm" and "VM" variable name?
And this;

# define ls a0 / LEFT IR SENSOR

Should be this;

#define ls A0 // LEFT IR SENSOR

along with the other # define statements?
C++ is case sensitive so vm variable is not the same as VM variable.

Can you post your working code please?

spycatcher2k:
@PRABHASKUMAR - you have crossposted this thread! I have reported you for this, and also added you to the 'do not help this person under any circumstances' list.

There's a list for that? Great idea.

The OP seems want people to simply write his code for him. Looking at those defines, I don't have much hope for his "advanced robotic vacuum cleaner" project.
