Have you ever faced an issue where your sketch uploads successfully, but the program doesn’t run as expected on your Arduino board? what are the the possible reasons and solutions for this problem.

Yes, this is a common issue that many Arduino users encounter.
If you're using an older Arduino board, you might need to select the "Old Bootloader" option under Tools > Processor
Try uploading a simple example sketch like "Blink" to see if the issue persists. If the Blink sketch works, the problem might be with your specific sketch.
