Introduction

Note: The gator:log will NOT function properly when used with the original gator:bit. Users should use the updated gator:bit (v2) with the gator:log for it to operate properly.

Most of you probably have done a science experiment that required data of some sort to be recorded...

The gator:log is the perfect data logging tool for your next experiment. With the automation of the data collection process, gone are the days of rushing around with a pen and composition notebook to simultaneously record data and your observations. Now, you only need to sit back and observe your experiment (or just wait for it to complete, if no observations are necessary).

The gator:log allows a student(s) to focus more on the experiment than watching a thermometer or sensor readout. Additionally, the micro:bit can still be used to provide a graphical display for observing changes in data, when a sensor readout is required. If tied in conjunction with the gator:RTC, stop watches on time based experiments can become a thing of the past too (with the added benefit of more accurate timing results)!

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

Required Materials

Note: The gator:log will NOT function properly when used with the original gator:bit. Users should use the updated gator:bit (v2) with the gator:log for it to operate properly.

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.
