1.下载安装Arduino IDE ，到官网下载自己的版本，然后安装即可。
网站：https://www.arduino.cc/en/software/
打开软件到设置语言为简体中文（英文好可以忽略），添加一个新的地址 https://dl.espressif.com/dl/package_esp32_index.json：
2.上面设置语言，下面添加一个地址https://dl.espressif.com/dl/package_esp32_index.json：
3. 安装库：在Arduino IDE中，转到“开发板管理”，然后搜索并安装“esp32”。
把自己的主板连接到电脑的USB端口，按下启动，然后选择一个网页示例：
选择AI Thinker ESP32-CAM这个主板和插入主板的端口，如下：
然后复制下面的代码替换CameraWebServer.ino文件内容并保存（自己修改一下wifi名称和密码）：
#include "esp_camera.h"

// WARNING!!! PSRAM IC required for UXGA resolution and high JPEG quality
// Ensure ESP32 Wrover Module or other board with PSRAM is selected
// Partial images will be transmitted if image exceeds buffer size
//
// You must select partition scheme from the board menu that has at least 3MB APP space.
// Face Recognition is DISABLED for ESP32 and ESP32-S2, because it takes up from 15
// seconds to process single frame. Face Detection is ENABLED if PSRAM is enabled as well
