"I’m having trouble with my Arduino project where the code I’ve written is not producing the expected output or behavior. I’ve double-checked the wiring, reviewed the code for errors, and tried different debugging methods, but the issue persists. Has anyone experienced similar problems, and what tro…

I break the components down and test a single one at a time. For instance, a display or sensor etc. I use the examples provided in most libraries. Once I each piece working then I add one device at a time to rebuild the program. My first test is to run the IDE example program "blink without dela…

Using a crystal ball, if You are experienced in that, is an option. Using temporary Serial.println at strategic points, printing strategic variables is another way.

[image] how to debug code in arduino IDE Programming Hi, Can anyone tell me how to debug the code written in arduino IDE.

Two most common causes are Inadequate variable or operand type, causing integer overflow and produce unexpected result Buffer overflow ( for example, OBOB ), causing program corruption and possibly produce unexpected result or program crash

You did ask a good question overall, with a good attitude! If the sketch is not long, posting it right off would have helped but with a long sketch, maybe not so much. Does it already print much? If not, "debug prints" may be your best tool.

Use a debugger ( if your board support this ), use debug prints if not. P.S. Must admit that 'crystal ball' is tempting ; - )

My crystal ball is always in the shop. Damned elves never get it right.

[image] anasrez: and what troubleshooting steps or solutions have helped you resolve unexpected output issues with Arduino? Posting a detailed schematic listing part numbers showing the wiring here really helped one time, and another couple times I posted my code using code tags.

Post your hardware devices. Post your wiring diagram. Post your code. Describe your expectations. Describe your observations.
