Micro:bit rides through brown-outs to teach energy harvesting

To teach children about programming processors that are powered by energy harvesting, Northwestern University engineers have made the Micro:bit educational computer power-aware and self-backup-ing. Three things are required: a modified version of Microsoft’s drag-and-drop MakeCode programming environment, an energy harvester such as a solar panel, and an SPI FRAM chip – the team is using Adafruit’s ‘SPI non-volatile ...
