I moved your topic to an appropriate forum category @subha129.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Thanks for the code. Is there a schematic and description to accompany it?

How to make a schematic you can post. - Using Arduino / Introductory Tutorials - Arduino Forum

[Idahowalker]

Help us help you.

Please follow the advice given in this link How to get the best out of this forum when posting code, in particular the section entitled 'Posting code and common code problems'.

Things that suck:

a). Images of code suck.
b). Images of error messages suck.
c). Code snippets suck.

Use code tags (the </> icon above the compose window) to make it easier to read and copy code for examination

Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.

Include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.

Post a schematic.

Post an image of your project.

Which Micro Controller are you using?

Is this simulator code?

Please describe the problem better then you just did.

this is a wrong code pls correct and send it if possible
