How to upload code to esp32-cam using Arduino IDE?

To upload code to an ESP32-CAM using the Arduino IDE, follow these steps:
Install the ESP32 Board Support Package:
If you haven’t already done so, you’ll need to install the ESP32 board support package in the Arduino IDE. Go to File > Preferences, and in the “Additional Board Manager URLs” field, add the following
Then, go to Tools > Board > Boards Manager, search for “ESP32”, and install the package.
Select the Correct Board and Port:
Connect your ESP32-CAM to your computer via USB. In the Arduino IDE, go to Tools > Board and select “AI Thinker ESP32-CAM”. Then, go to Tools > Port and select the port that corresponds to your ESP32-CAM.
Open Example Sketch:
To test uploading code, you can use one of the example sketches provided with the ESP32 board support package. Go to File > Examples > ESP32 > Camera, and select the example sketch that best fits your needs. For example, you might choose “CameraWebServer” to create a simple web server that streams video from the ESP32-CAM.
Modify the Code (Optional):
Depending on your project requirements, you may need to modify the example sketch to suit your needs. For example, you might want to change the Wi-Fi network credentials or adjust camera settings.
Upload the Code:
Once you’ve modified the code (if necessary), click the “Upload” button in the Arduino IDE toolbar. This will compile the sketch and upload it to your ESP32-CAM. Make sure your ESP32-CAM is in programming mode (press the “RST” button while holding down the “FLASH” button) before starting the upload process.
Monitor the Serial Output (Optional):
After uploading the code, you can open the Serial Monitor in the Arduino IDE (Tools > Serial Monitor) to view debug messages and monitor the behavior of your ESP32-CAM.

That’s it! You’ve successfully uploaded code to your ESP32-CAM using the Arduino IDE. You can now disconnect the ESP32-CAM from your computer and test its functionality according to the code you’ve uploaded.
