Making a step counter

This unit brings together all the four programming constructs: sequence, repetition, selection and variables whilst also utilising a physical device - the micro:bit. Pupils begin with a simple program to build and test and then take on three new projects, with each adding more depth and complexity.

Sensing movement with physical computing

Designing your program first helps you plan what it needs to do.

You should write your program before designing it.

Using algorithms makes programming easier.
