Besides helping you test prototypes of your wacky Arduino ideas, breadboards ensure your components can be reused once you’re ...

You learn tons about everything from circuit concepts and assembly ... simply driven by the PWM outputs of the Arduino. It’s not a hugely complex project, but it teaches so much.

and also because all of the circuit schematics are available for all of the components in the build. For those reasons, it could be a great gateway project into more complex FM builds.
