micro:bit Remote Data Logging Demo
Watch the video for a demo showing the use of two, radio linked, micro:bits for remote data logging. One micro:bit is measures the light level when button A is pressed (this could be automated). The reading is transmitted by radio to the second micro:bit which records the data as a .csv file on the computer that it has been paired with via the USB cable.
The data in the .csv file can then be opened in a spreadsheet application for analysis.
Note that these are v2 micro:bits but the system will work if using v1 micro:bits.
