Gravity: UV Index Sensor Code for micro:bit

This project demonstrates how to use MakeCode programming to read ultraviolet (UV) data from the Gravity: 240370 Ultraviolet Index Sensor with a micro:bit. Users will learn to add the UV sensor library to MakeCode, create a program, and upload it to the micro:bit.
