I'm working on a project using Mindflex and Arduino to make a mind controlled wheel chair.
Here's the link to the full instructions: https://frontiernerds.com/brain-hack
When we tried to open the serial moniter there was no output. What do I do?

Welcome to the forum

Please do not post pictures of code or Serial monitor output

You have not even posted your whole sketch

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the < CODE/ > icon above the compose window) to make it easier to read and copy for examination

First thing to check is that the baud rate set in the code and the baud rate selected on serial monitor match.

The screenshots of part of the code and the Serial monitor originally posted and subsequently removed by @mhchung32_2010 showed that the baud rates matched

I've tried that multiple times. Are there any other trouble shooting meathods?

Start by posting your code and details of any hardware attached to your board, how it is wired and how the project is powered. Have you by any chance got anything plugged into pons 0 and 1 ?

Does a simple print of "Hello World" in loop() work ?

Load the Hello World sketch and see if that gives you an output. If so it is your code, if not it is hardware, probably a bad cable.
