Beginner Project: Two Tone Siren

Siren is a very straightforward device but for beginners it is an excellent starting point since it directly interacts with real world via sound and is a great morale booster for next, more advanced projects that shall come.

Consisting of a very low part-count it can also be built on breadboard. This siren in particular uses two NE555 timers which can be replaced with just one NE556 - if you can get your hands on one. It is also called "Sweeping Output Siren" as seen elsewhere.
