Good day to all! In today's article, I would like to tell you about a rather interesting and useful product that I found on the well-known Aliexpress website. I think many have heard or used small black tweeters themselves, which when powered up are very loud and intrusive, which is amazingly peep, such things are popularly called tweeters, and abroad they are called “bazzer”, and this is not an ordinary speaker, as many might think. A small problem with such tweeters is that they were not originally intended for microcontrollers
Arduino, and this is normal, but sometimes in projects it is necessary to use such a tweeter and connect it directly to Arduino, it seems to be easy, just bring one of its minus “legs” to Gnd, and the second to one of the analog pins, but these “pins” are intended for control, not for power, so this connection will not be very good, and the sound of the tweeter will not be what you need. In this case, a small module will help, which we will talk about today.
This module is a small board on which are located: the tweeter itself, micro-parts and three outputs, for power and connection to the Arduino, the whole chip of this module is in the third output, it is designed to control the board, thanks to this the tweeter will work at full strength and its connection will be much easier.
This useful module is not worth a lot and I think almost everyone can afford it, its price at the time of writing is 19 rubles, delivery is paid and costs 45 rubles.
I think many will need such a module.
Well, thank you all for your attention and good luck in future projects, friends!
