This model of controlling lighting using a smart phone is performed using the Arduino MKR1000 microcontroller, which is capable of wireless communication with a smart phone. The microcontroller is powered using a USB-A connector/cable with a computer on which the program code has been entered. The smart phone uses the free application Blynk, in which a two-key (ON/OFF) project was created. The Arduina MKR1000 contains the program code containing the wireless network to which it must be connected. After sending the signal from the smart phone (by the user) to the microcontroller, the relay receives the signal and closes the circuit (“- pole/neutral conductor”) after which the consumer connected to the relay receives electricity. In this case, the consumers are two light bulbs, one LED and one classic light bulb. For this model, a two-channel relay is required. This allows for the control of lighting with a smart phone, which could be lighting in a residential structure, building, offices or similar when the user is not inside the structure.
