BirdCalls Turns an Old Payphone Into a Birdsong Project
Arduino Blog
EDITOR BRIEF
A yellow payphone in Takoma Park, Maryland plays bird sounds instead of a dial tone when someone presses a number. The project, called BirdCalls, was created by David Schulman and has run on Arduino hardware for nearly a decade. It uses recorded birdsong to turn an obsolete object into something people can interact with in public.
INSIGHTS
This shows how simple hardware like Arduino can turn a creative idea into a real-world experience. If you’re learning coding or AI, try building a small interactive project that reacts to buttons, sound, or sensors.
