Features of the ESP32 AI Thinker Board

The ESP32 AI Thinker Board comes with an array of impressive features. Firstly, it is very reasonably priced, making it an attractive option for beginners and hobbyists. With a cost similar to that of an Arduino board, it offers great value for money. The board is capable of running on both 5V and 3.3V power supplies, giving you flexibility in your projects.

In terms of GPIO pins, the ESP32 AI Thinker Board offers around six to seven pins, which may seem limited compared to other boards. However, with a little creativity, these pins can be utilized effectively to build small robots or control devices using the L293D motor driver chip. The board also features a built-in camera, which adds a whole new dimension to your projects, allowing you to capture images and even stream video.

Working with the ESP32 AI Thinker Board

Setting up the ESP32 AI Thinker Board for your projects is a straightforward process. To begin, you'll need to install the ESP32 board manager in your Arduino IDE. The board manager can be found in the "Tools" section of the IDE. Simply search for "esp32" and install the required Package. Once installed, select the ESP32 AI Thinker Board as the target board in the IDE.

Next, you'll need to connect the board to your computer using an FTDI chip. Make sure to connect the ground and 3.3V pins correctly. You will also need to connect the RX and TX pins, but remember to reverse them on the ESP32 board. Additionally, a jumper pin needs to be connected while uploading the code, but removed afterwards for proper functioning of the board.

Setting Up the ESP32 AI Thinker Board

To get started with the ESP32 AI Thinker Board, follow these steps:

Install the ESP32 Board Manager: Copy and paste the link provided in the description box into your browser to access the ESP32 board manager. Click "OK" and navigate to the "Tools" section in the Arduino IDE. From there, go to "Board Manager" and search for "esp32". Once you find the ESP32 board manager, click "Install" and wait for the installation to complete.
Select the Board: After the installation is complete, go back to the "Tools" section and select the ESP32 AI Thinker Board from the list of supported boards.
Upload the Code: Open the example sketches and navigate to the "esp32" folder. From there, select the "camera" folder and then the "camera_server" sketch. In this sketch, you'll need to modify the Wi-Fi name and password to match your network. Once the modifications are done, click the "Upload" button in the Arduino IDE. Make sure to press the reset button on the board when prompted.
Configure the Serial Monitor: After the code is uploaded, open the serial monitor and change the baud rate to 115200. The serial monitor will display the IP address of the ESP32 board, which you can use to access the camera stream.

Connecting and Configuring the Camera

The ESP32 AI Thinker Board comes with a built-in camera that needs to be connected and configured correctly. Carefully unpack the board and locate the camera module. Insert the camera module into the designated slot on the board, ensuring that the camera is facing upwards. Take caution when handling the board to avoid damaging the camera.

You will also Notice a small antenna part on the board for the external Wi-Fi. The power supply for the ESP32 board is provided by the FTDI chip, with the GPIO3 and GPIO1 pins used for data transmission. Make sure to connect the jumper between the appropriate pins during the programming phase, and remove it once the code is uploaded to ensure proper operation of the board.

Streaming and Capturing Images

Once the ESP32 AI Thinker Board is set up and the code is uploaded, you can start streaming and capturing images. Open Google Chrome or any web browser and enter the IP address displayed in the serial monitor (e.g., 192.168.0.101). A web page will open with the camera stream. Click on the "Start Streaming" button to view the live feed from the camera.

By adjusting the control options on the web page, you can change the orientation of the camera and apply different effects. You can also select various resolutions to suit your needs. Experiment with these settings to get the desired output and explore the capabilities of the ESP32 AI Thinker Board.

Conclusion

The ESP32 AI Thinker Board is a cost-effective and versatile development board that offers exciting possibilities for projects involving IoT, robotics, and more.
