​The CAN protocol is the abbreviation of Controller Area Network. This protocol was originally proposed by the automotive industry. With the development of intelligentization in the automotive industry, more and more electronic instruments are installed inside the car, making the signal line wiring more and more complicated.

Un modulo WiFi, spesso chiamato modulo serial-to-WiFi, è un componente incorporato che integra un chip WiFi, circuiti RF e un intero stack di protocollo di rete (IEEE 802.11 b/g/n/ac/ax e TCP/IP) in un pacchetto compatto.

ESP32 and esp8266 are two popular wireless system-on-chips (SoCs) developed and widely used in Internet of Things (IoT) projects and smart devices. The esp8266 is a cost-effective solution for simpler tasks. ESP32 offers higher performance and more functions, and is suitable for more complex application scenarios. Both are very popular and have rich development resources and project cases in the open source community. The following is an introduction to these two bullet points.

When it comes to connectivity for IoT devices and embedded systems, the esp8266 Wi-Fi module is a topic of much concern. esp8266 is a low-cost, high-performance Wi-Fi module launched by and widely used in IoT applications, smart home devices, and various embedded systems.

The method of using WiFi module​ to achieve intelligent control can be divided into multiple steps, including selecting a suitable WiFi module, connecting hardware, writing software, and realizing network communication and intelligent control. The following is a guide to using esp8266 WiFi module
