Arduino Class - Using An SD Card In Your Project


Location image of event venue


Come join us at Education Center in Plano TX to learn how to interface an SD Card with the Arduino.

SD cards have matured over the years. Their sizes have expanded to many gigabytes, and their prices have dropped to a few cents per gigabyte. Compared to build-in memory, SD cards offer a really good mass storage solution. On the Arduino, an SD card can be used with the appropriate hardware extension and with an easy to use library that comes with the IDE. Your Arduino Ethernet shield ( comes with a micro-SD card slot, but you can also get them as a separate breakout board. In this class, we will use a dedicated, small and cheap break-out board.


Reading and writing to an SD card, Part 1 of 3 ( (13:50) In Part 1, I will show you how to connect the SD card module to the Arduino, format an SD card, and verify that it can be used.

Reading and writing to an SD card, Part 2 of 3 ( (10:30) In Part 2, I will show you how to store sensor measurement data to the SD card, and import to Excel for charting.

Reading and writing to an SD card, Part 3 of 3 ( (9:45) In Part 3, I will show you how to use a recursive function in order to excaustively traverse files and directories. Parts Needed:

Arduino UNO ( SD card mass storage using a cheap breakout. ( Course work for this class comes from Arduino Step By Step ( which has over 20 hours of content in 110 lectures. These classes are designed for anyone interested in learning electronic design and C programming. No experience is required. Access to the course material is free at our meetups.
