I am gettig error message that 'check was not declared in the scope'. I have done privious projhect with the same code but it do not gets this error but this time it is getting an error. Today coding is

#include <AFMotor.h>

//Objects
AF_DCMotor motorRight(1, MOTOR12_64KHZ); // create motor #1, 64KHz pwm

//Constants and variable
char dataIn = 'S';
char determinant;
char det;
int vel = 255; //Bluetooth Stuff
int god = 255;
int aod = 255;
int bod = 255;
int cod = 255;
int dod = 255;

void setup() {
  Serial.begin(9600); // set up Serial library at 9600 bps
 
 //Initalization messages
  Serial.println("SAARTHI");
  Serial.println("Mr.PhotoBox");
  Serial.println("Reday for use Lets's Click it !!");
 
  pinMode(8, OUTPUT);  //1 Led
  pinMode(9, OUTPUT);  //2 Led
   pinMode(10, OUTPUT);  //3 Led
   pinMode(11, OUTPUT);  //4 Led
   pinMode(12, OUTPUT);  //5 Led
  
  
  
  //turn off motors
  motorRight.setSpeed(0);
  motorRight.run(RELEASE);
 
}

void loop() {

**>  det = check(); //call check() subrotine to get the serial code<**

And my privious codding was

#include <AFMotor.h>


//Objects
AF_DCMotor motorRight(1, MOTOR12_64KHZ); // create motor #1, 64KHz pwm
//Constants and variable
char dataIn = 'S';
char determinant;
char det;
int vel = 255; //Bluetooth Stuff


void setup() {
  Serial.begin(9600); // set up Serial library at 9600 bps
  pinMode(9, OUTPUT);  //FrontLed
  pinMode(8, OUTPUT);  //BackLed
   pinMode(10, OUTPUT);  //Horn
  
 
  //Initalization messages
  Serial.println("Mr.robot");
  Serial.println("Reday for working Run It");
  
  //turn off motors
  motorRight.setSpeed(0);
  motorRight.run(RELEASE);
}

void loop() {
  det = check(); //call check() subrotine to get the serial code

Please help me out please it's urgent.

I am getting this issue

Please helpppppp!!!!!!!

TomGeorge · May 9, 2021, 7:33am

Hi,
Welcome to the forum.

Where is the check() function.
You code looks cutoff at the bottom in both versions.
Is it the complete code?
What Arduino are you using?

Thanks.. Tom...

krishna_agarwal · May 9, 2021, 7:33am

I am using arduino uno R3

What to do please help

Please help it's urgent please please please

PLEASE post the complete code.
Your code is not complete! ! !

I've merged your cross-posts @krishna_agarwal .

Cross-posting is against the rules of the forum. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend 15 minutes (or more) writing a detailed answer on this topic, without knowing that someone else already did the same in the other topic.

Repeated cross-posting will result in a suspension from the forum.

In the future, please take some time to pick the forum board that best suits the topic of your question and then only post once to that forum board. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide you will find at the top of every forum category. It contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

krishna_agarwal · May 9, 2021, 7:36am

No this is not a complete code
I had just send a short code sh

Sorry for it

But please help me

TomGeorge · May 9, 2021, 7:40am

Hi,
The code you posted does not have
check() function in it.

That is what the error is telling you.

Did you write it, or are you using an edited code from another source?

Tom...

krishna_agarwal · May 9, 2021, 7:40am

It was copied

TomGeorge · May 9, 2021, 7:42am

Hi,
Have you got the original?

Your codes are not complete...

This is the full code please help

anon73444976 · May 9, 2021, 7:46am

 if (dataIn == '12')

Oops

Your check function is embedded in another function.
C++ doesn't allow that.

krishna_agarwal · May 9, 2021, 7:47am

My issue is det = check

anon73444976 · May 9, 2021, 7:48am

No, your current issue is with check.
That's easily fixed.
Not so easy to fix what I highlighted

krishna_agarwal · May 9, 2021, 7:51am

How can i fix that?
I am unable please help🤷‍♂️

anon73444976 · May 9, 2021, 7:53am

Your loop function definition should be complete before your check function definition starts.

I think also the switch in the loop function is incomplete.

Fix that first.
