Display Emotion Badges

Overview

In this activity, you will make an emotion badge using the micro:bit. You will
program the micro:bit to show different faces, like happy, sad, or surprised,
on its LED display. This activity will help you to understand how the micro:bit’s

buttons work and how you can use them to control what happens on the screen.

The Micro:bit has many different parts, and one of them is its programmable
buttons. On the front of the micro:bit, there are two buttons, called Button

A and Button B. By pressing these buttons, you can make the micro:bit do
different things. For example, you can use them to change what shows on the
screen or to control other actions in your projects.
