Elegoo Mega2650 - Was ok, now not ok

Development Tools Uploading

Hi

I'm new to Arduino. I'm building points for my model railway and the other day testing was fine. I have come to set up more servos today and have an issue with the hardware I think. Below are the error messages. When I used it last I'm sure the board selected was Adafruit Circuit Playground and usbmodem (USB) as the port. But this isn't working. I tried with Arduino Mega2650 selected, again via USB and still not working - Would appreciate any help. I'm using Macbook on Ventura OS. Thanks, Rik.

Sketch uses 11320 bytes (39%) of program storage space. Maximum is 28672 bytes.
Global variables use 618 bytes of dynamic memory.

Format everything from

and forward as code to make it easier to follow.

Sorry but I don't understand, I'm copying video tutorials and the files are already written so just copying them into Arduino. So do I enter 'Sketch uses' into the software to format everything? As for forwarding as code, hmmm ok will look into that.

Yep, edit your post, mark everyting from Sketch uses and click the code button.

Done - thanks.

Thank you, now it's clear what is your own typing and not.

When you wanna upload the sketch, are you using Upload or Upload using a programmer?

I just click on upload (the arrow on the top bar), I got the calibration.ino file online. I can hear the servo moving a tiny bit every now and again.

tried with Arduino Mega2650 selected, again via USB

This would be the right setting.

Did it ever work on your MB and Ventura?

Yes, it worked today no problem.
