In this lesson, we learn how to use a Micro SD card. We learn how to write to the card and how to read text. How to log voltage from a potentiometer to the memory card. How to save the data in CSV format so we can open it in a spreadsheet like Excel for plotting and other analysis.

This is a simple way to create two files simultaneously on a microSD card.
