'''Arduino development environment setup:''' 
ESP8266 supports Eclipse/Arduino IDE and other development tools. It is relatively simple to use Arduino. The following is how to build the Arduino development environment: 
1. Install Arduino IDE 1.8.9 or the latest version; 
2. Open the Arduino IDE, click File--Preferences in the menu bar, enter the preferences and click Add Network in the "Additional Development Board Manager URL". 
[http://arduino.esp8266.com/stable/package_esp8266com_index.json%EF%BC%9B http://arduino.esp8266.com/stable/package_esp8266com_index.json] 
[[File:LC-WF-1-8-3.png]] 

3. Click Tools--Development Board--Development Board Manager in the menu bar, and then search for "ESP8266" to install Arduino's support package for ESP8266 2.5.2 or the latest version; 
[[File:LC-WF-1-8-4.png]] 
'''Note:''' Since the download URL is from a foreign country, the access speed is relatively slow, and there may be download errors. Just try a few more times when the network is good. 

'''Program download:''' 
1. Use jumper caps to connect IO0 and GND pins, prepare a TTL serial port module (for example: FT232) and plug it into the computer USB; GND, RX, TX, 3.3V are respectively connected to GND, TX, RX, 3.3V of the external TTL serial port module V; 

2. Click Tools--Development Board in the menu bar, and select the development board as ESPino (ESP-12 module); 

3. Open the program to be downloaded, click Tools--Port in the menu bar and select the correct port number; 

4. After clicking "Upload", the program will be automatically compiled and downloaded to the development board;

5. Finally, disconnect the connection between IO0 and GND, power on the development board again or press the reset button to run the program
