How does RTC work on an Arduino board?
RTC Library. This library allows an enables an Arduino based on SAMD architectures (es. Zero, MKRZero or MKR1000 Board) to control and use the internal 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.
What kind of oscillator does an RTC use?
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 the Arduino Zero) whose frequency is 32.768 kHz (same frequency used in quartz clocks and watches).
What can I do with a zero RTC board?
Zero, MKRZero or MKR1000 Board) to control and use the internal 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.
What kind of battery is needed for RTC?
A button sized lithium battery or any battery in the 3V range, connected through a diode to the 3.3V pin, is enough to keep RTC alive if the CPU is put in sleep mode before the standard USB or VIN power is disconnected. Corrections, suggestions, and new documentation should be posted to the Forum.
