Shake and sounds

What is it?

Shake your micro:bit to hear a cheerful tune. This project is ideal for students new to the micro:bit as it only uses two blocks.

How it works

• Your micro:bit contains an accelerometer which detects movements.
• When the accelerometer detects a shake gesture, the program instructs the micro:bit to play a tune.
• Inputs allow us to put data into a computer or device. In this project, the input is the shake gesture.
• An output is the processed information that is sent out from a computer. In this project, the output is the music that is played from the micro:bit’s speaker.

What you need

• a micro:bit
• MakeCode editor
• battery pack
• optional speaker and crocodile clips if you are using a micro:bit V1

Code your project

Here are the blocks you need to make the project - now put them together.

Step-by-step instructions

1. Open the project to find the blocks you need using the buttons above.
2. Find and select the play melody block.
3. Put the play melody block inside the on shake block.
4. Download the program to your micro:bit, attach a battery pack, and try it out!

Make it your own

• Try different tunes... Open the melody editor within the play melody block. Select the Gallery tab and choose a different pre-written tune to play. Which is your favourite?
• Play the tune faster or slower... Adjust the bpm (beats per minute) option inside the play melody block to a smaller number to play the tune more slowly. Or add a higher number to make the tune play more quickly. You can choose numbers from 40 to 500, either by using the sliding scale or typing them in.
