Connecting Digital Tubes with Arduino Development Boards

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:

SH_CP:

Understanding the Complex Relationships Between Microcontrollers, ARM, MCU, DSP, FPGA, and Embedded Systems

First, "embedded" is a concept that lacks a precise definition, with various books providing their own interpretations. However, the main idea is the same: compared to general systems like PCs, embedded systems are specialized systems, structurally simplified, retaining only the necessary parts in hardware and software while discarding the unnecessary ones. Therefore,
