First, you will need to include the ArduinoOTA and WiFi libraries at the top of your sketch:.Here is an example of code that demonstrates how to set up OTA updates on the ESP32 using the ArduinoOTA library: You can then use the ArduinoOTA library to perform the update. To perform OTA updates, you will need to set up a web server that serves the firmware update file and configure the ESP32 to connect to this server and download the update file. OTA updates are commonly used for devices that are installed in hard-to-reach locations or that need to be updated frequently, such as Internet of Things (IoT) devices. OTA updates are useful because they allow you to update the device remotely, and they can save time and effort by eliminating the need to physically access the device to perform the update. Over-the-air (OTA) updates refer to the process of updating the firmware or software of a device wirelessly, without the need to physically connect it to a computer.

OTA updates allow you to update the firmware of your ESP32 wirelessly, without the need to physically connect it to a computer. The ESP32 is a microcontroller that is capable of performing over-the-air (OTA) updates.
