Buzzer Circuit. There are two types are buzzers that are commonly available. The two most common technologies used in buzzer designs are magnetic and piezo.
Many applications use either a magnetic or a piezo buzzer but the decision regarding which of the two technologies to use is based upon many different constraints. The two most common technologies used in buzzer designs are magnetic and piezo. The loop routine will make this run again and again making a short beeping sound.
You can also use tone pin frequency duration function.
There are two types are buzzers that are commonly available. You can also use tone pin frequency duration function. It is very small and compact 2 pin structure hence can be easily used on breadboard perf board and even on pcbs which makes this a widely used component in most electronic applications. A simple loud buzzer circuit trembling sound is creating a kind of ring circuit that provides a strange sweetness of general bell.
