Подключение 2-x, 3-х и 4-х символьных светодиодных индикаторов к Ардуино

This video will present the pinout of 2, 3 and 4-character seven-segment LED indicators and an example of their connection to Arduino. We will look at how to connect a 4-digit LED indicator directly to the Arduino UNO. As well as connecting the LED indicator to the Arduino using the 74HC595 shift register. The video shows an example of a sketch for working with a seven-segment LED indicator in the Arduino IDE. The sketch is versatile and suitable for working with 1, 2, 3 and 4 character LED indicators. It is only necessary to change the connection of the Arduino pins (or shift register) in accordance with the pinout of a specific LED indicator.
