First time running Arduino (on Mac), Blink throws errors

[Mr_Horizon]

Hello everyone, I hope you can help me!

I bought the Arduino Starter Kit. I followed the book setup and downloaded the latest non beta Software for my Macbook (OS Version number is 12.0.1).

I opened the Blink demo, and tried to compile it. It stops with this error message:

Followed by many rows of errors for libraries, like this one:
Invalid library found in /Users/henningknopp/Documents/Arduino/hardware/espressif/esp32/libraries/AzureIoT: no headers files (.h) found in /Users/henningknopp/Documents/Arduino/hardware/espressif/esp32/libraries/AzureIoT

After this, I downloaded the latest VCP driver (the troubleshooter guide suggested it) and tried to update libraries. The former did nothing, the latter just added more library error messages.

Do you know what to do? I'm a bit disheartened as I thought Arduino was a very easy intro into electronics and now not even the built-in demos can run.

ESP32 is not Arduino, link to the kit you purchased

[Mr_Horizon]

I didn't know I had to link anything - I will have a look.

Several years ago someone connected a microcontroller to my laptop for a day to show me something, maybe there is still settings leftover from that time? But in a fresh install? That would be unfortunate.

@killzone_kid thank you for pointing me in the right direction!

Please know it is the first time I am doing this, I had no clue that you need to tell the Arduino software what board is connected, or that there could be somehow old settings leftover even in a new install.

However, the Blink demo is still showing an error I do not understand. Some device cannot be opened... could you help me with this one as well?

You also have to tell the software which port your Arduino is attached to.

[Mr_Horizon]

Now it works!

Thanks to both of you.
