    The aim is to teach young people the basics of electronics and how to use a soldering iron (since they update me on the electronic evolution that runs too fast for me). So I buy, and I will in the future too, these simple circuits for their practice. It is clear to me that these kits are cheap, but a sponge to protect the pins of the socket and the integrated circuit would not hurt (look at the photo in what condition they arrived).

    Полученная плата отличается от представленной на рисунке. В комплекте нет разъёмов. А главное - собрал два модуля и оба не работают! При включении динамик сразу трещит, а при нажатии на кнопку немного меняется частота треска. Изменение напряжения питания влияет на громкость,

    Nice set, easy to assemble, because the placing of the components is printed on the pcb. It works good with 5V. Door bell sound is very simple, just two different frequencies.

    It is very good, but it does not contain IC socket.
