Buzzer 3-24V continuo
Este modelo de buzzer es de tipo activo por lo que su funcionamiento es muy sencillo, solo es necesario alimentar el buzzer para emitir sonido. Se recomienda utilizar un transistor NPN (2n2222) entre el Arduino y el buzzer. Activar el buzzer es tan sencillo como enviar un pulso alto (3v-24v) al buzzer.
Buzzer es un transductor electroacústico que produce un sonido o zumbido continuo o intermitente de un mismo tono (generalmente agudo). Sirve como mecanismo de señalización o aviso y se utiliza en múltiples sistemas, como en automóviles o en electrodomésticos, incluidos los despertadores.
Inicialmente este dispositivo estaba basado en un sistema electromecánico que era similar a una campana eléctrica pero sin el badajo metálico, el cual imitaba el sonido de una campana. Su construcción consta de dos elementos, un electroimán y una lámina metálica de acero. El zumbador puede ser conectado a circuitos integrados especiales para así lograr distintos tonos. Cuando se acciona, la corriente pasa por la bobina del electroimán y produce un campo magnético variable que hace vibrar la lámina de acero sobre la armadura.
Posee 2 orificios de instalación para facilitar su montaje.
