Good day to all! Today, I will show you a very interesting product, this
electronic key for Arduino modules. I think it will be useful to many masters in their projects, for example, it can be used to create a hidden electronic safe or just as a device for recognition in any simple home-made protection system, for example, on this basis, you can also make a door lock in your room, which will be quite spectacularly, although I think now it’s already possible to purchase a pretty good module for arduino with a built-in fingerprint for one or two thousand rubles, but as I said, it costs a little expensive and not everyone can afford it be, well, the module costs only 90 rubles, and I think almost every Arduinschik can afford such a module. By the way, if you want, I can write a similar article about a module with a fingerprint, if of course it will be interesting to you, in general write comments, I will be glad to read it.
This module works with a voltage of 3.3 V, which allows you to power it directly from the built-in board
Arduino back-up power, and I want to say that it is quite convenient.
By the way, the data transfer rate in the module is as much as 10 Mbit per second! Agree, very, very good speed for such a cheap and inexpensive module.
In general, to whom this product seemed interesting or if you have been looking for something like this for a long time, then the link to the product is under the article.
Well, thank you all for your attention and good luck in future projects, friends!
