Arduino Mega 2560 "Failed to Send Command to Seriel Port"
Hello Everyone,
This is my first post on this forum so my apologies in advanced if the format isn't 100% correct. About 5 weeks ago I started a college course titled "CEIS101 Intro to tech and Info Systems".
I've sailed through the class but I ran into one error with my Ardunio Mega 2560. We were given a PDF (It is attached) and are shown a diagram on how to assemble the "smart home system". After putting it together I am supposed to connect the system to my computer and run a series of code that is also given to us and attached in the PDF.
When connecting the Arduino and running the code, it throws me a series of error messages that are attached at the bottom of the page that essentially say "Failed to send command to seriel port". I'm extremely new to the Arduino and I'm not quite sure if this is a coding error or a hardware error with my project.
I was hoping someone on here can point me in the right direction. Thanks so much in advance.
Error Messages I received:

Inside is the project, sorry about that.

This is probably a key message:
You need to track down why the device is not found.
Does your development board have a usbmodem?

Yes, it is a USB Type B that is connected to the device it self that is adapted into a USB Type C that connects to my computer.
Here is a link to the PDF of the project I was assigned.
Inside is every line of code that is "supposed" to be working.

The problem is not the with the PC but with the embedded processor. For some reason the "driver" for the hardware is not being found.
Are you sure that "/dev/cu.usbmodem14301" is actually correct? Could there be a typo on that line? Perhaps try "/dev/cu/usbmodem14301".

I just ran the program on my PC instead of my Mac and the error seems to be solved. Thank you so much for your help. The issue appears that my Mac was not picking up from the right location on my computer. When running the code on my PC the error completely went away.
