Computer wireless WiFi boot card PCIE remote boot stick ESP-12S Wireless PC Power Switch

## Wireless PC Power Switch based on ESP-12S
### **Project Highlights**
- ESP-12S itself is used as a web server, **no third-party software is required, convenient and fast**
- While supporting remote control, **it does not affect the use of the physical power button**
- Arduino is used for programming, **code is available for download and modification**
- Can display the current computer running status and refresh automatically
- Support switch operation judgment to avoid invalid switches
- Add remote one-key restart function (use with caution)
- **Already board verified**

### **Project Scalability**
- Since it is a **page written in HTML**, you can change it as you want. (Although I don't know how to write HTML, the codes given are all in very simple HTML syntax)
- Because it is a server itself, it needs to realize remote control through the function of external network penetration (**This project requires external network penetration to realize control outside the LAN**, and many people use third-party software such as Blinker)

### **Usage Notes**
- Motherboard Wiring Instructions

The following figure is an introduction to the relevant pins of my motherboard. I designed this boot card based on my motherboard. Most motherboards are similar. For details, please refer to the electrical schematic diagram.
![Motherboard Wiring Instructions] In fact, the four types are also marked on the PCB, **which are power supply PW, restart RES, LED light LED, and hard disk light HD**.



- Program Modification Instructions

Use Arduino to write the program. Generally speaking, **you only need to modify the corresponding SSID and PASSWORD to burn and use it**.

The process of connecting to WiFi on the power on will use the serial port to print the connection status. The connection status and successful connection will print the current IP address, and the serial port baud rate is 115200.

If the obtained IP address is 192.168.1.10, then the link to the management page is 192.168.1.10/Dashboard

- A warning will appear when the machine is turned on again to prevent accidental touch, and this page will automatically return after 3 seconds

- The shutdown and forced restart operations are the same, and will not be demonstrated again.
