How do you save data from an Arduino-based device to a memory card? Fortunately, a microSD card and SD card breakout board now make this an easy task.

He devised a method to inject addressing data into these unused bits, allowing him to address up to 64 different memory chips for a potential of 2 MB of storage.

Finally, [Paul] takes a look at exponential filters, which are recursive, use less memory, and can be tweaked to respond to changes in different ways.

Right now, I'm trying to figure out if I can fit a wireless library, RTC library, JSON parsing library, and all my string data in the Arduino memory footprint, or if I have to drop back to ...

This is an Arduino project called 'Simon Says'. It is essentially a memory game with LEDs and push buttons. The Arduino will play us a sequence of LEDs and the user will try to recreate this pattern ...
