Step 1: Make it
What is it?
Program your micro:bit to play a famous tune – or one of your own.
How it works
- Connect headphones, or amplified speaker to pins 0 and GND on your micro:bit to hear the sound.
- Pin 0 works as an output when we play music on the micro:bit.
- This program uses musical notes to play a famous French folk tune. ‘Frère Jacques’ repeats each bar twice. We could program micro:bit to play the same notes again, but it’s much easier to use iteration (also known as a loop). This program uses loops that play each bar twice to save having to program the same notes twice.
- Recognising patterns like this part of computational thinking, a way of making sure computer programs are as efficient as possible, using the smallest amount of code to perform a task – or piece of music!
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
- Speed it up or slow it down by changing the tempo.
- Complete the full tune. The extra notes you’ll need are GAGFEC, CGC but you’ll need to play the first 4 notes for half a beat, not 1 beat. Remember to use loops to make your code more efficient.
- Program other tunes using sheet music or make up your own.
