The micro:bit orchestra is a makecode extension for making musical robots, digital compositions and an interconnected synchronized mesh of musiC making micro:bits. So far, I have made two large and one tiny installations using the microbit orchestra at The Norwegian Museum of Science and Technology, the Northern Norwegian Science Center and Ås Science Center, along with one big portable version for use in school visits in Troms. I am also building an ongoing collection of portable micro:bit orchestra instruments for use when playing live concerts around the world.
