RTCZero Library
The RTCZero library is available from 86Duino Coding 212, and provides the API of Arduino Zero’s RTC library to control and use the on-board RTC (Real Time Clock).
A real-time clock is a clock that keeps track of the current time and that can be used in order to program actions at a certain time. Most RTCs use a crystal oscillator (like in all 86Duino boards and the Arduino Zero) whose frequency is 32.768 kHz (same frequency used in quartz clocks and watches). Namely this the frequency equal to 2^15 cycles per second and so is a convenient rate to use with simple binary counter circuits.
