This is a set of ten (10) electric buzzers. GREAT VALUE!
These operate at 1.5 volts - so a single AA, AAA, C or D battery would work!
Sound frequency they produce is 400Hz (fairly pleasant frequency for buzzers.)
These are perfect for science and electronics projects such as Telegraph / Morse Code circuit, Buzz Wire game, Pest Repellent and any other circuits where sound signalling is required.
These are great for demonstrating simple in-parallel and in-series circuits and teaching electricity and electronics.
They come with 6 inch (15cm) long black/red connection wire leads for easy, no-solder connection to batteries and switches.
