Make basic circuit so LEDs flash up. (they can code LEDs to flash already in Arduino)
Learn how to create a tune using the TONE function.
Link the tune to flashing lights.
Create the circuit on a piece of card
Put the circuit on to a small chip so it works independently. (my job)
Take home, add power and watch it light up.
It’s going to be a fun, creative project. They can even paint the card as well so it looks all pretty and artistic.
The only real cost is the chip – and that’s £2!! The speakers will be hacked from broken headphones – something that’s very common in primary schools. I like this because it shows that broken does not mean broken.
The project will also teach the physics of sound – looking at frequency and pitch. Plus coding of course.
A great lesson. Covers the concepts of pitch, frequency and how speakers work. Next step is to introduce the notes and get them to create their own music. Hopefully then they will be able to put them into a card.
