使用一個usb轉ttl連接esp32-cam:(切記一定要將io0接gnd)
在您的Arduino IDE中,轉到文件>示例> ESP32 >相機并打開CameraWebServer示例:。

在上傳代碼之前,您需要在以下變量修改可以連接的wifi:
const char* ssid = “REPLACE_WITH_YOUR_SSID”;
const char* password = “REPLACE_WITH_YOUR_PASSWORD”;
然后,確保選擇正確的相機模塊。我使用的是AI-THINKER模型。
因此,請注釋所有其他模型,并取消注釋該模型:
// Select camera model
//#define CAMERA_MODEL_WROVER_KIT // Has PSRAM
//#define CAMERA_MODEL_ESP_EYE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_PSRAM // Has PSRAM
//#define CAMERA_MODEL_M5STACK_V2_PSRAM // M5Camera version B Has PSRAM
//#define CAMERA_MODEL_M5STACK_WIDE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_ESP32CAM // No PSRAM
#define CAMERA_MODEL_AI_THINKER // Has PSRAM
//#define CAMERA_MODEL_TTGO_T_JOURNAL // No PSRAM
要上傳代碼,請按照以下步驟操作:
1)轉到工具>主板,然后選擇AI-Thinker ESP32-CAM。
2)進入工具>端口,選擇ESP32連接的COM端口。
3)然后,點擊上傳按鈕上傳代碼。
不久之后就會上傳成功,如果上傳不成功或者連接不了,請確認接線是否正確,是否將io0連接gnd
通過串口可以獲得網址,將網址粘貼到瀏覽器即可,注意一定要和你的電腦在同一局域網下
