Imagine how you might adapt this project to the theme of pollinators, bats and biodiversity loss.
Imagine if you could blow into a microphone and cause a windmill to spin. You can with the Breath Controlled Windmill. While one of the simpler Arduino projects for kids, it’s great for beginners and teaches how sounds can be used with electronics.
LED lights make the windmill look great and make it stand out even more when it’s spinning. When you finish, turn off all the lights, blow into the mic and enjoy the show. While it doesn’t technically spin, the lights make it seem as if it is.
