Is the baud rate in your serial monitor set to 115200 (I suspect not)

As the previous answerer said, this type of garbage value appears in the serial monitor due to a baud rate mismatch. Kindly check that.

I'm pretty sure the baud rate is correct. Here's a screenshot of what I see. The gibberish output came from pushing the button.

I don't see an option for a 74880 baud in the list?

The Arduino IDE did have 74880 added to to it. Not sure if the new V2 has it, I have not upgraded on my system.

I prefer to use CoolTerm to see serial data. See HERE for details.
