Animated animals

Beginner | MakeCode, Python | LED display | Iteration

Step 1: Make it

What is it?

Animate your own pictures on the micro:bit display.

How it works

  • This program creates an animation on the micro:bit’s LED display output by using a built-in image and one you create yourself.
  • First it shows the duck built-in image and then shows a modified version, which moving all the dots (pixels) down one row.
  • It shows the two different pictures one after the other, with a half second (500 millisecond) delay, to make it look like a duck bobbing up and down on the water.
  • An infinite loop keeps the micro:bit showing the image sequence until you unplug the micro:bit.
  • Using loops in computer programmes is also known as iteration. They help you create efficient compact code without needlessly repeating the same instructions.

What you need

  • micro:bit (or MakeCode simulator)
  • MakeCode or Python editor
  • battery pack (optional)
  • optional graph paper to sketch out your own animal designs

Step 2: Code it

Step 3: Improve it

  • Try modifying and animating different built-in images like GIRAFFE and RABBIT.
  • Create your own images from scratch using graph paper to sketch out your designs.
  • Make longer animated sequences to tell a story.
  • In Python, use different numbers to change the brightness of different pixels. 9 is the brightest, 1 is the dimmest and 0 is off.
