It’s Just a Matter of Time…

Last time I wrote a post, I had gotten to the point where my anemometer reads pulses from the Hall Effect sensor, calculates the wind speed, and prints that data to a serial monitor (either the built-in monitor in the Arduino IDE, or a third party monitor like PuTTy). Since then, I’ve finished the next hurdle in the programming which is storing that data to a MicroSD card.

Wiring up the MicroSD card is relatively straight forward, and writing to the card is as simple as writing to the Serial monitor, so it wasn’t a difficult hurdle to overcome, but getting one of the necessary steps taken care of gives me that warm, fuzzy feeling inside. I’ve also included in the Arduino Code a rudimentary checking system to verify if the Arduino can communicate with the MicroSD card, and if not, skip writing to it and just print the data to the Serial Monitor. This way, if the end user isn’t worried about historical wind speed data, they don’t need to stick one in and they can just hook it up with a USB cable to view the data.

Maybe I need to think about integrating some sort of monitor to the Arduino, like an LCD screen, so a computer isn’t needed if you don’t want to store the data.
