I have an older Arduino (2018) that doesn't work on my new computer while it works on my old laptop.
When I upload a sketch the pins don't work but it takes it.
I have tried several programmers but it doesn't seem to matter.
It is strange that when I upload the blink with the built-in LED it works.
Can anyone help me?
Which board?
What exactly do you mean by "don't work"?
Please post the sketch.
[pre]It seems the pins are not working at all, I have an Arduino Uno.
I'm sure it isn't broken because it works on an older version of the Arduino IDE.
