Jukebox

Step 1: Make it

What is it?

Make a music machine that plays different tunes at the push of a button.

These two videos show you what you'll make and how to code it:

How it works

• A jukebox is a machine that plays different songs when you put a coin in and choose which tune you want to hear by pressing buttons.
• This micro:bit jukebox uses headphones or speakers connected to make sound like we did in the Make some noise project.

• Connect micro:bit pin 0 to the tip of your headphone plug, and GND to the longer part of the headphone plug.
• When you make sound with the micro:bit, pin 0 becomes an output.
• This program plays different built-in tunes if you press input button A or button B.

What you need

• micro:bit (or MakeCode simulator)
• MakeCode or Python editor
• battery pack (optional)
• a pair of headphones, buzzer or amplified loudspeaker
• two crocodile clip leads

Step 2: Code it

Step 3: Improve it

• Change the tunes, for example try PRELUDE or ENTERTAINER. You can find a list of all the built-in tunes you can use in Python here.
• Show different pictures, letters, numbers or words depending on which tune you picked.
• Make it play a random tune if you shake it.
