Saving the Data: Working with SD Card

Saving data to a memory card is often required if the data needs to be analyzed later. With Arduino boards, this is done by using the breakout boards of SD or micro-SD cards. The SD cards have been on the market for more than 20 years and are still commonly used, including the Arduino-based projects. In this chapter, we will go over some simple setup and wiring for the purpose of writing data files on the memory card for later usage.
