Hi all, I am beginner of Arduino. I just purchased this board from digikey.
But, the board seem does not work at normal.
I follow the following video provided by the manufacturer (https://groupgets.com/manufacturers/getlab/products/c12880ma-breakout-board) to go through the test. But, no spectral plot comes out after running the Processing script.
May I know what I can do to ensure the C12880MA works well?
