The gator:RTC is a real-time clock. This means that the gator:RTC can be used as a supplemental data logging tool, in conjunction with the gator:log to add precise timing to your data collection. Therefore, student(s) can put down that stopwatch and start focusing more attention on what is happening in their experiments. Other applications for the gator:RTC include time lapse photography, timers and alarms, clocks, and etc.

This tutorial will show you how to get started using this gator:RTC with the gator:bit (v2) in the micro:bit development environment.

Required Materials

To get started, you'll need a micro:bit to control everything. Each of the products below includes a micro:bit, but the kit and bundle also include some additional accessories that you may want as well.
