Lesson 4
Making a conductivity tester
Introduction
Pupils learn how to use the BBC micro:bit’s pins as inputs. They plan, write, test and debug MakeCode programs to use micro:bits to test the electrical conductivity of materials.
Learning objectives
- To plan, write, test and debug programs
- To write programs that use selection
- To write programs that use inputs and output
