Getting Started with ESP32 Cam Module and Solve Fatal Error

The ESP32-CAM is a powerful and versatile microcontroller with built-in Wi-Fi and Bluetooth, making it ideal for various IoT projects. Here’s a step-by-step guide to help you get started with your ESP32-CAM on a Windows PC.

Step 1: Gather Your Components

Before you begin, ensure you have the following components:

- ESP32-CAM module

- USB to TTL/Serial adapter (such as FTDI or CP2102)

- Jumper wires

- Breadboard (optional)

- Micro USB cable

Step 2: Install Arduino IDE

1. Download Arduino IDE: Visit the [Arduino IDE download page](https://www.arduino.cc/en/software) and download the Windows installer.

2. Install Arduino IDE: Run the installer and follow the on-screen instructions to install the IDE on your PC.

Step 3: Install ESP32 Board Support

1. Open Arduino IDE: Launch the Arduino IDE.

2. Open Preferences: Go to `File` > `Preferences`.

3. Add ESP32 URL: In the "Additional Board Manager URLs" field, enter the following URL: `https://dl.espressif.com/dl/package_esp32_index.json`

4. Open Boards Manager: Go to `Tools` > `Board` > `Boards Manager`.

5. Install ESP32: In the Boards Manager window, search for "ESP32" and click "Install" on the "esp32 by Espressif Systems" entry.

Step 4: Set Up ESP32-CAM in Arduino IDE

1. Select Board: Go to `Tools` > `Board` and select `AI Thinker ESP32-CAM`.

2. Select Port: Connect your USB to TTL adapter to your PC and select the appropriate COM port under `Tools` > `Port`.

Step 5: Wiring the ESP32-CAM

1. Connect the ESP32-CAM to the USB to TTL Adapter:

- ESP32-CAM | USB to TTL

- 5V | 5V

- GND | GND

- U0R | TX

- U0T | RX

- IO0 | GND (for programming mode)

Step 6: Uploading the Code

1. Open Example Sketch: Go to `File` > `Examples` > `ESP32` > `Camera` > `CameraWebServer`.

2. Modify the Sketch: Find the following lines in the sketch and update them with your Wi-Fi credentials:

const char* ssid = "your-SSID";
const char* password = "your-PASSWORD";

3. Select Board Settings: Ensure the following settings are selected:

- Board: `AI Thinker ESP32-CAM`

- Flash Mode: `QIO`

- Flash Frequency: `40MHz`

- Partition Scheme: `Huge APP (3MB No OTA)`

- Upload Speed: `115200`

4. Upload Code: Click the upload button. While uploading, press and hold the `RESET` button on the ESP32-CAM.

Step 7: Running the ESP32-CAM

1. Open Serial Monitor: Go to `Tools` > `Serial Monitor` and set the baud rate to `115200`.

2. Reset the ESP32-CAM: Disconnect the IO0 pin from GND and press the `RESET` button on the ESP32-CAM.

3. View Output: The Serial Monitor will display the IP address of your ESP32-CAM.

4. Access the Web Server: Open a web browser and enter the IP address displayed in the Serial Monitor. You should see the camera feed from your ESP32-CAM.
