Module 3.4: Real Time Clock

Welcome to the fourth part of Build Your Own Data Logger module 3. In these videos, we'll get into the process of writing our data logger application and carrying out our proof-of-concept strategy.

Our course directory has a full list of modules and videos with links. Follow our Build Your Own Data Logger playlist on our Youtube channel to catch every module as it goes live, and register for our full course to be the first to know about our module releases, live Q&A events, and course news!

In Module 3.4, we learn about how real time clocks (RTCs) are used in instrumentation. Timekeeping plays a central role in scientific field instrumentation. It’s used to timestamp data, synchronize multiple standalone devices, and also controls power management. We discuss how RTCs work, how outdoor conditions affect clock accuracy, and the different types of clocks and their accuracy. We also learn how to access and control the real time clock on the WildLogger board, set the date and time, and read it in different formats.
