Microbit Programming Concepts and Algorithms

This lesson introduces students to key concepts in computing, including algorithms, sequences, programming, and output. It provides practical examples and exercises to reinforce understanding. The lesson also introduces the BBC Microbit, a small programmable device, and guides students through creating a simple project using the Microbit. Students learn to navigate the Microbit website, write programs, and explore various features of the device through tutorials.

What is an algorithm?
