A part of the TECgirls Great Green Hack Week, this video tutorial walks kids through a micro:bit project where they build their own plastic pollution counter using makecode editor. This project is perfect for kids 7-12 who are just getting started with coding and using a micro:bit. If you don't have a micro:bit you can still code using the simulator within the makecode website. This video can be used by coding clubs and as a part of a kids STEM lesson. No previous coding experience needed.
