Good day to all! In today's article, I would like to tell you about a very interesting product from the Aliexpress website. This product is called ttp223 and is a miniature touch button for arduino. The module can be useful to many, I think it will prove itself in projects for the home, as well as to make a hidden lock for example for a box or drawer, there are many options for use, the main thing is to include fantasy. I also think that it can be used by those who do not have money for an expensive module with a fingerprint scanner, though then it will also have to figure out how to hide it from prying eyes.
I think the same capacitive button can be made easily at home, from foil or any other conductor of electric current, I saw how something was done even from bananas, but it was a little different. The module is not very expensive, so you can simply order. The cost at the time of writing was 89 rubles and 11 rubles delivery.
The module can be powered from 2 volts to 5.5 volts, so it can be powered directly from the arduino.
In general, the product is quite useful.
Well, thank you all for your attention and good luck in future projects, friends!
