Happy 2014! We’re particularly happy to be making the first release of the SleepySketch library for writing low-power Arduino sketches.

Clearly saving battery power means getting the XBee radio to sleep at the behest of the Arduino. This turns out to be fairly simple, but does require modifying the XBee shield slightly.

Keeping the microcontroller asleep as much as possible is a key goal for a sensor system, so it makes sense to organise the entire software process around that.
