This tiny, affordable module combines the powerful ESP32 processor with a built-in camera, making it perfect for a variety of applications, from security systems to AI projects.

In this guide, we’ll walk you through the process of setting up your ESP32-CAM with the Arduino IDE, step-by-step. Let’s get started!

What You’ll Need

ESP32-CAM module
ESP32-CAM-MB Micro USB Download Module
Micro USB cable
Arduino IDE installed on your computer

Step 1: Install the Arduino IDE

If you haven’t already, download and install the Arduino IDE from the official Arduino website.

Step 2: Install the ESP32 Board in Arduino IDE

Open the Arduino IDE.
Go to File > Preferences.
In the “Additional Board Manager URLs” field, add the following URL
Click OK and go to Tools > Board > Board Manager.

				
					https://dl.espressif.com/dl/package_esp32_index.json

Click OK and go to Tools > Board > Board Manager.
Search for “ESP32” and install the “ESP32 by Espressif Systems” package.

Step 3: Connect the ESP32-CAM to the ESP32-CAM-MB:

Insert the ESP32-CAM module into the ESP32-CAM-MB Micro USB Download Module.
Connect the Micro USB cable to the ESP32-CAM-MB and then to your computer.

Step 4: Select the Board and Port

Go to Tools > Board and select AI Thinker ESP32-CAM.
Ensure the correct port is selected under Tools > Port.

Step 5: Prepare the Arduino IDE for Programming:

Open a new sketch in the Arduino IDE.
Go to File > Examples > ESP32 > Camera > CameraWebServer to open the example sketch.

Step 6: Configure the Sketch:

In the CameraWebServer sketch, locate the following lines and ensure they are uncommented:

				
					#define CAMERA_MODEL_AI_THINKER

Enter your Wi-Fi credentials in the appropriate section of the sketch

				
					const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";

Step 7: Upload the Sketch:

Hold down the RESET button on the ESP32-CAM-MB while connecting to your computer. This will put the module into programming mode.
Click the upload button in the Arduino IDE. You should see the “Connecting…” message. If it takes too long, press the RESET button on the ESP32-CAM-MB again.
Once the sketch is uploaded, open the Serial Monitor (Ctrl+Shift+M) and set the baud rate to 115200 to see the IP address assigned to the ESP32-CAM.

Step 8: Access the Web Server:

Open a web browser and enter the IP address displayed in the Serial Monitor. This will take you to the camera web server interface.

Troubleshooting:

Reset the Module: If the upload fails, press the RESET button on the ESP32-CAM-MB and try uploading the sketch again.
Check Connections: Ensure the ESP32-CAM is properly seated in the ESP32-CAM-MB.
Serial Monitor: Use the Serial Monitor to check for any error messages that can help diagnose issues.

Additional Tips:

External Antenna: If your ESP32-CAM has a poor Wi-Fi signal, consider using an external antenna if your module supports it.
Power Supply: Ensure your USB port can provide enough current. The ESP32-CAM can be power-hungry, and insufficient power can cause instability.

By following these steps, you should be able to successfully use the ESP32-CAM with the ESP32-CAM-MB Micro USB Download Module in the Arduino IDE.
