Actually I presumed OP would use the same LED/resistor of the original circuit. But also didn´t know pin 13 had a resistor in the past. So, thanks!
But yes sorry, all upload code were failed, I also try with something with Serial.printI() and it fails.
Turn on verbose output for compiling and upload in your preferences then try the Blink sketch again.
After uploading it copy the full message from the bottom of the screen and post it here again in

avrdude done. Thank you.
This indicates that the code is compiling and loading successfully.
It looks like you used Blink.ino when you generated this.
Is the on board led blinking?
Yes, but the led blink 3 times very fast, infinitely, like before uploading the code. It does not blink as requested in the code.
In Preferences, please check the box which says "Verify Code after Upload" and see what the verbose output indicates when that is checked.
There is indeed a error here:
avrdude: verification error, first mismatch at byte 0x0000
0x62 != 0x0c
avrdude: verification error; content mismatch
Failed uploading: uploading error: exit status 1
Hi @ada
It looks like you are using the 2.0.xxx IDE.
Load the 1.8.19 IDE and see if it works.
What OS are you using?
Tom..
I will check in a few hours, my mac Os is Monterey version 12.0.1
This is an indication of a problem with the bootloader code on the AT328.
https://forum.arduino.cc/t/solved-verification-error-content-mismatch/436352
You can either try to burn a new bootloader using another Arduino or a USBASP programmer. There are plenty of guides to be found online.
Alternatively, since you have a socketed AT328 on your board, you can purchase a new chip which is programmed with the bootloader. Not all AT328 chips are sold this way, so make certain of what you are buying.
I changed the AT328 and It actually works now. Thanks you all !
