Getting to Know Arduino:
Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform. It consists of two parts: the hardware part is the Arduino circuit board used for circuit connections; the other part is the Arduino IDE, which is an application that provides a programming development environment, integrating code writing, analysis, compilation, and other functionalities into a single software.
Arduino can sense the environment through various sensors and can also control lights,
Introduction to Digital Tubes
The pins related to data of 74HC595 can be divided into three categories:
DS: Serial data input, connected to a certain digital I/O pin of the microcontroller.
Q0~Q7: 8-bit parallel data output, can directly control 8 LEDs or the 8 pins of a seven-segment digital tube.
Q7′: Cascade output terminal, connected to the DS of the next 74HC595 to achieve cascading between multiple chips.
There are four pins related to control of 74HC595:

If your answer is yes, then today I would like to introduce a platform that is very suitable
Introduction to Arduino
Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform. It includes hardware (various models of Arduino boards) and software (Arduino IDE). It was developed by a European team in the winter of 2005, consisting of Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, David Mellis, and Nicholas Zambetti.
