Understanding Sequencing and Timing
The micro:bit LED display consists of a 5 × 5 grid of LEDs that can be individually
controlled to create images and animations.
In this activity, the display is used to show a beating heart animation by
alternating between two images: a large heart and a small heart.
Image Display: The heart images are shown by lighting up specific LEDs in a
5x5 grid. Different patterns of LEDs create the large and small heart shapes.
Timing and Sequencing: The program switches between the heart images every
half second, controlled by a timer to keep the images changing at a steady rate.
Looping: An infinite loop in the program repeatedly shows the heart images in
sequence, making the heart animation appear to beat continuously.
