all pictures will have a different filename-you won’t have problems with overwriting previous files when the ESP32 resets.Using date and time on the picture filename has several advantages: The idea is to apply the concepts you’ll learn with this example to your own projects. For demonstration purposes, the ESP32-CAM will do this task over and over again on the loop(). The photo is saved to the microSD card – its filename contains the date and time.It gets the current date and time from the NTP server.It initializes the camera and the microSD card.The ESP32 connects to an NTP server to initialize the date and time with the correct timezone.The ESP32-CAM connects to your router via Wi-Fi (this is needed so that we can get time from an NTP server).In this tutorial, we’ll show you a simple example that does the following: The following diagram shows a high-level overview of the example we’ll build. ESP32 NTP Time – Setting Up Timezones and Daylight Saving Time.

We have a detailed tutorial explaining how to set timezone and daylight saving time when getting time from an NTP server using the ESP32:

We’ll use the current date and time on the pictures’ filenames. Getting Date and Time with the ESP32 (Accurate Timezone and Daylight Saving Time)

ESP32: Guide for MicroSD Card Module using Arduino IDE.

To get familiar with handling files with the microSD card and the ESP32, you can take a look at the following tutorial: Your microSD card must be formatted as FAT32. We’ll save the photos taken with the ESP32-CAM on the microSD card.

Installing the ESP32 Board in Arduino IDE (Mac OS X and Linux instructions).

You can follow the next tutorial to install the ESP32 add-on, if you haven’t already: So you need the Arduino IDE installed as well as the ESP32 add-on. We’ll program the ESP32 board using Arduino IDE.
