Lesson Details
Key learning points
- Text and images can be displayed by physical computers using arrays of light such as the micro:bit's LED display matrix.
- Sensors can be used to create programs that respond to their environment.
Common misconception
The micro:bit can only show letters and numbers.
The micro:bit's LED display can show more than letters and numbers. It can show shapes, images, and patterns. The display matrix can be programmed to output any desired pattern.
