Help us help you.

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Images of code suck.

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

How to get the best out of this forum

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

Images of error messages suck.

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.

If you are using a 9V battery like this.

Don't.

The search box is a useful tool.

For instance, using the words "9v battery" in the search box one could find lots of reasons why this may be a bad idea.

Other search words include "level shifter", "round", "millis()",

GREAT REPLIES SO FAR
They should be grouped as a sticky for new BEGINNER questions.
