Name badge

Beginner | MakeCode, Python | LED display | Input/output

Step 1: Make it

What is it?

Turn your micro:bit into a scrolling name badge with just a few instructions.

name 'Sam' scrolling across the micro:bit LED display

How it works

  • The micro:bit’s LED display output can show words and numbers as well as pictures.
  • This program shows you how to scroll text across the screen to let people know your name and show a picture.
  • An infinite loop keeps the sequence going until you unplug the micro:bit from its battery or USB lead.
  • Scrolling text on LED displays are often used to show bus and train information. What other uses can you think of for scrolling text on micro:bits?

What you need

  • micro:bit (or MakeCode simulator)
  • MakeCode or Python editor
  • battery pack (optional)

Step 2: Code it

Step 3: Improve it

  • Make different messages appear if you press button A or B.
  • Spell out your name one letter at a time.
  • Design a way of wearing your micro:bit badge using thread, tape or velcro. (Don't use safety pins as the metal could damage your micro:bit.)
