News - New Product Friday: A Bas… | about 7 months ago

Spark-Star++ for magnetic rotary position sensor/breakout. I had great success with a MLX90316, a generic 8-pin SOIC to DIP breakout board, and a couple of components along with the Arduino library here: http://interface.khm.de/index.php/lab/experiments/rotary-positionsensor-mlx90316/
The library and write up made this relatively easy to work with. The sensor is incredibly accurate.

I think maniacbug’s port of JeeLabs RTClib (grabbed link from comment above) would help with with date calculations.

Product BOB-10160 | last year

I was experiencing the 45/25/165 18:85:85 / 0/0/0 0:0:0 issue as well. Turns out I had the wiring wrong (I’m a beginner). I’m using the Mega 2560 and I have it wired up as follows:
GND – GND
VCC – 3.3v
SQW – GND
CLK – 52
MISO – 50
MOSI – 51
SS – 8
battery is attached
It now works with both Sparkfun’s example and maniacbug’s library (which is awesome!).
