Building Arduinos

Tonight was Sam’s second time to go to North Branch Library and their meet-up group for Arduino. Sam says there’s a lot to explain about Arduino. “The possibilities are endless,” he says. “You can build drones. But today, it was mostly about building electronic musical instruments.”

For example, he built this little theremin today.

He calls it a light theremin because it changes its sound frequency based on different levels of light.

He also built this little keyboard. “It’s not exactly a keyboard,” Sam says. “It’s just buttons.”
