Sound emotion badge

Step 1: Make it

What is it?

Make an emotion badge that expresses how you feel in sounds as well as pictures.

What you'll learn

• How to use the new micro:bit's built-in sounds as outputs to add personality and expression to your projects.

How it works

• The micro:bit with built-in speaker can play new expressive sounds. This project plays a happy sound when you press input button A to match the happy icon on the LED display output.
• It plays a sad sound when you press button B to match the sad face icon.
• When you press the touch logo, it plays the 'spring' sound to match the surprised face on the LED display.

What you need

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

Step 2: Code it

1from microbit import *
2import audio
3
4while True:
5    if button_a.is_pressed():
6        display.show(Image.HAPPY)
7        audio.play(Sound.HAPPY)
8    if button_b.is_pressed():
9        display.show(Image.SAD)
10        audio.play(Sound.SAD)
11    if pin_logo.is_touched():
12        display.show(Image.SURPRISED)
13        audio.play(Sound.SPRING)

Step 3: Improve it

• Experiment with the different new expressive sounds like 'giggle', 'hello' and 'twinkle'.
• Modify the program with different emotion icons, or draw your own.
• Add an animation to go with each expression.
