Start with ESP32-CAM

Heute ist Stammtischzeit:

Wer Lust hat, kann sich gerne beteiligen. ;)
  • I use Arduino IDE test my new toy, an ESP32-CAM, now I’ll show you how to start with it.

    First of all, we need get ready our hardware:

    • An ESP32-CAM dev board
    • A camera, like OV2640 or OV7670, I use the OV2640 for test

    Ps:I think the OV2640 for test, the OV7670 better for projects


    3、TTL to USB module

    Next step, software part:

    Arduino IDE(https://www.arduino.cc/en/software/)

    There are Arduino IDE for Windows, for Linux and for Mac OS


    Step 3

    Put your ESP32-CAM link to TTL to USB module

    TTL to USB 5V link ESP32-CAM 5V

    TTL to USB GND link ESP32-CAM GND

    TTL to USB TXD link ESP32-CAM U0R

    TTL to USB RXD link ESP32-CAM U0T

    Like this:


    Step 4

    Take your TTL to USB module into USB interface of your computer, and open your PC Manage——Device Manager——Ports, remember your COM

    Step 5

    Open your Arduino IDE, File——Preferences, take https://dl.espressif.com/dl/package_esp32_index.json into Additional Boards Manager URLs



    Step 6

    Click Tools, find Board, choose AI Thinker ESP32-CAM, find CPU Frequency, choose 160MHz(WiFi/BT), find Port, choose your own COM(in Step 4)


    Step 7

    Click File——Examples——WiFi——WiFiScan


    Step 8

    Remove // in front of #define CAMERA_MODEL_AI_THINKER

    Step 9

    Put your ssid and password into here

    Step 10

    Link IO0 and GND of your ESP32-CAM(important)

    Upload the code to your ESP32-CAM dev board

    Remove IO0 to GND jumper wire

    Open Tools——Serial Monitor, you can find a IP address, copy it and paste in your browser

    You can use your camera now, if you want Face Detection, Resolution must be CIF(400x296)

    Enjoy it and share it to your friends!
