I. Arduino Development Environment Setup
1. Download and Install Arduino IDE
Download the Arduino IDE from the official Arduino website. During installation, accept the license agreement (clicking "I Agree" ✔️) and proceed by clicking "Next" ▶️.
The installer allows choosing installation options, such as installing the Arduino software, USB driver, creating Start Menu and Desktop shortcuts, and associating .ino files. The default installation path is typically on the C drive, but you can click "Browse" ?️ to select a different location.

2. Specify Installation Folder
Choose the desired installation folder. For example, you can install it in a folder named 'arduino' on the D drive (e.g., D:\arduino\). Click "Install" ⚙️ to begin the installation.

3. Complete Installation and Prepare Hardware Files
Wait for the installation to finish. Navigate to the Arduino installation directory and locate the 'hardware' folder. Download the 'espressif' file and unzip its contents into the 'hardware' directory. This step is crucial for adding ESP32 board support to the Arduino IDE.

4. Configure Arduino IDE for ESP32-CAM
Open the Arduino IDE. From the 'Tools' menu, select the appropriate development board (e.g., "ESP32 Dev Module" or a specific ESP32-CAM model like "HK ESP32-CAM-MB"). Ensure the correct COM port is selected.

II. ESP-CAM Video Streaming and Photographing Example
1. Open the Camera Sketch
After downloading the necessary ESP32-CAM firmware or examples, navigate to the 'Camera' directory. Double-click the 'Camera.ino' file to open it in the Arduino IDE.

2. Upload Code to ESP32-CAM
With the 'Camera.ino' sketch open, ensure the correct ESP32-CAM development board and COM port are selected in the 'Tools' menu. Click the "Upload" button (often depicted as a rightward arrow ▶️) to compile and upload the code to the ESP32-CAM module.
3. Monitor Serial Output and Connect to Video Stream
Open the Serial Monitor from the 'Tools' menu. Select the baud rate 115200. Reset the ESP32-CAM development board. Observe the serial output for connection details, including an IP address (e.g., 192.168.4.1).

4. Access Video Streaming and Capture Photos
Connect your mobile phone to the ESP32-CAM's Wi-Fi network (SSID will be similar to "ESP-xx:xx:xx:xx:xx:xx"). Open a web browser on your phone and enter the IP address provided in the serial monitor (e.g., 192.168.4.1).
On the web interface, press the "Start Streaming" ▶️ button to view the live video feed. To capture a photo, press the "Get Still" button. The captured photos are saved to the SD card in a randomly named file.
