Hi, what does the monitor say EXACTLY?
A picture of your project and a CAD or picture of your circuit would also help, in jpg, png or pdf.
You have all the information your end, you started the project, this makes you more informative than we are, we need to catchup and the only way we can do this is for you to read our requests and answer them.
Your display should say
"MMA8452 Basic Example"
first then go to displaying data.
Do you have the monitor set to 57600 baud?
Press reset button on arduino to make sure program initiates.
Tom...Hope to help......
