Here the signal is simply exchanged, which is usually provided when a variable-type current passes through the zero variable. These variables are usually represented by radio frequency pulses at a frequency 120 KHz with duration 1 Milliseconds.

Dignity
Speaking about the virtues of an Arduino-based smart home, the following points should be noted.
Great opportunities in terms of preparing the work of the entire mechanism. That is , the user can independently write a program that can implement algorithms of different levels of complexity.
If desired , the system can work autonomously due to the presence of its own controller.
Downloading a program is easy becausethat a programmer is not required for this, but everything is done using an interface USB , Since the bootloader is simply installed in the microcontroller.
Very low price components of the system. This is due to the fact that different manufacturers do not have exclusive rights. For this reason, the Arduino architecture is classified as open.

The presence of open source code allows the user to directly control the mechanism of the smart home.
Accessibility is that the user chooses which sensors he needs.
Versatility and ability to implement the most interesting ideas. There are no instructions or standards for what an Arduino-based smart home should be. This means that the user can make the system the way he wants , since the owner is not limited to anything in terms of installing sensors in the bedroom or kitchen.
The possibility of a self-firmware loader.
The presence of a pin connector for processor boards Arduino , Which allows programming within the system.
