This change applies to the following projects:

  • [Module 1] Unit 2: Preparing Arduino IDE for the ESP32-CAM

2) CameraWebServer Example

The CameraWebServer example provided in the Arduino IDE no longer supports face recognition and detection. We updated the eBook to reflect those changes The same example has changed slightly its interface. We took new print screens to reflect this new version.

This change applies to the following projects:

  • [Module 1] Unit 3: Camera Web Server with Video Streaming.

3) ESPAsyncWebServer and AsyncTCP libraries by ESP32Async

We now use the latest forked versions of the ESPAsyncWebServer and AsyncTCP libraries by ESP32Async.

This change applies to the following projects:

  • [Module 2] Unit 5: Take Photo and Display in Web Server
  • [Module 2] Unit 6: Web Server SD Card Photo Manager: Capture, View and Delete
  • [Module 3] Unit 3: Take and Email Photo with Web Server
  • [Module 4] Unit 2: Video Streaming Web Server with Sensor Readings

4) Instructions to create an app password

We updated the instructions to create an app password on the projects that use email notifications.

This change applies to the following projects:

  • [Module 3] Unit 1: Send Photos via Email
  • [Module 3] Unit 2: Motion Detector with Photo Capture and Email Notifications
  • [Module 3] Unit 3: Take and Email Photo with a Web Server

5) Home Assistant

We updated the instructions to include the ESP32-CAM IP camera in Home Assistant.

This change applies to the following projects:

  • [Module 4] Unit 3: Video Streaming IP Camera

6) ngrok

The instructions to use ngrok to access the video streaming from anywhere were also updated.

This change applies to the following projects:

  • [Module 4] Unit 6: ESP32-CAM IP Camera Access from Anywhere in the World

7) Updated PWM Commands

The projects that use PWM were updated to be compatible with version 3 of the ESP32 core.

This change applies to the following projects:

  • [Module 1] Unit 5 ESP32-CAM Flashlight and External Pushbutton

That’s it for now.

Thanks for your support.
