My serial monitor is not working on IDE 2.3.4.
It was working before, but after I updated it stop showing me anything.
Does anyone know what happened?
MY board: R3 UNO
I am pretty sure I connect the hardware correctly.
My sketch:
What did you update?
from IDE 2.3.3 to 2.3.4
Should have asked earlier: which operating system? Max or Linux?
I’m using Mac. But I have tested it on Windows system as well.
what does the Ouput says when you upload the code?
don't show us a picture, copy the text & paste in code tags the content of the compile & upload log.
problem solved! Thanks for the help!
Usually people who asked for help have the curtesy to share what the solution they found was in case someone else was facing the same issue…

sorry I didn’t explain how i solved in the end.
I press the check button but didn’t click the upload button, that’s why my sketch was only check but not sent to the board..
