The code is not uploading

i was making a proyect from school, i used the playshield and playboard plates, but at the moment of uploading the code, it splash this error:

avrdude done.  Thank you.

i will be so grateful if anyone can say me how to fix this problem, and i have only 2 days to deliver the proyect

Hi @oscarpalomo. Please add a reply here on this forum thread to tell us which Arduino board you are using.

Please be as specific as possible as some Arduino boards with similar names have significant differences and the forum helpers can only provide effective assistance if we are aware of which one is being used.

If you aren't sure how to describe which board you are using, you can provide the link to the online product listing you bought the board from and we'll proceed based on the information found there.

What are those? I've never heard of a playshield or a playboard.

If I understood correctly you meant something like this: https://www.youtube.com/watch?v=qpYfAS_aSr0, https://www.youtube.com/watch?v=eqqcKwaaWsY, when you said playshield and playboard right?
But still it doesn't say which MCU you are using, however according to the error, you need to RESET MCU and change Baud to usual for Arduino - 9600 baud
