Now that we`ve covered the basics in tutorials 1-10 (you have watched them all right! ), it`s time to start pursuing some more complex projects! In this episode, we`ll utilize an SD card shield from cooking-hacks. com to create a datalogger. First, I`ll walk you through the process of reading from, and writing to an SD card. Then, we`ll utilize som
e of our knowledge from tutorials 4, 6, 7, and 8 to add several sensors that we can poll periodically using our datalogger. The logger will record sensor values to its SD card in a useful format so that we can later use a computer program like Microsoft Excel to visualize the data. Download the schematics and source code first so you can reference them while you watch the video. For the first time, I`m using fritzing to draw the circuit schematics. So, take a look at them, and let me know what you think!
