First Steps with Microbits for data-logging and modelling

Since the BBC micro:bit became commercially available last year there is much more information now available about how to access the many features which make the micro:bit such a powerful tool for cross-curricular STEM projects.  This guide is mainly concerned with how to access the micro:bit's sensors to capture data.  This includes using the free S2Bot App to monitor values read from the micro:bit via Bluetooth.  That also gives Scratch 2 a new set of blocks for communicating with the micro:bit.  You can also program the micro:bit using the PXT (or other) editor to turn it into a handheld meter e.g. for light, temperature, magnet field strength etc.  Data from these experiments can be transferred manually into spreadsheets such as Excel for manipulation, display and modelling.  There is an introduction to the free GeoGebra software for mathematical modelling and also to the free Tracker software for ways to gather data from video clips of the dynamic experiments.  The main free tool currently available for wireless data-logging (telemetry) is the Bitty Data-logger App for Apple and Android. The activities are mainly centered around the  science and mathematics aspects of the curriculum - or just for fun tinkering.  This is the companion piece to the First Steps with Microbits for Control and Physical Computing which has more of a slant towards DT, computing and electronics.
