(Last Updated On: March fifteen, 2022)
ESP32 Cam Programming using Arduino, Description:
In this tutorial, you volition acquire how to program the ESP32 Cam using Arduino Uno or Arduino Nano. We will also get through all the basic settings including the ESP32 Cam board director installation. In the end, I will as well explain how to gear up the most common errors including the Detected Photographic camera not supported and the camera probe failed with error 0x20004.
There is also another issue that you might confront while working on the ESP32 Cam that is the ESP32 module keeps resetting automatically. I volition practically show y'all, how to fix these errors and run your ESP32 Camera Module without any problems. Without whatever further delay Let'due south become started!!!

What is ESP32:
ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.
What is ESP32-cam?
The ESP32-CAM is a small photographic camera module with the ESP32-S chip that costs approximately $ten. Also the OV2640 photographic camera, and several GPIOs to connect peripherals, information technology also features a microSD carte du jour slot that tin be useful to store images taken with the camera or to shop files to serve to clients.

ESP32 connectedness with Arduino Uno or Arduino Nano:
Connect the Reset Pivot of the Arduino with the GND.
Connect the 100 pin of the ESP32 Cam with the GND Pivot, for this you can use a female to female person type jumper wire.
Connect the 5V and GND pins of the ESP32 Cam with the Arduino's 5V and Basis.
Connect the Receive Pin of the ESP32 Cam with the RX pin of the Arduino.
Connect the Transmit Pin of the ESP32 Cam with the TX pivot of the Arduino.
The ESP32 Cam interfacing with the Arduino is completed. Now, allow's go to the estimator screen and install the ESP32 Cam board.
ESP32-Cam Board Manager Installation:
Make certain the latest version of the Arduino IDE is installed on your estimator. Re-create the link given beneath.
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
At present, open up the Arduino IDE, click on the file menu and and so click on the preferences and simply paste the URL.
Now click on the Tools menu, boards, and click on the boards managing director, search for the ESP32 and install, this can take several minutes. Side by side cheque if the desired board is installed,
As you tin see the ESP32 Wrover Module is available.
ESP32 Cam Settings:
Next, become to the Wink Mode and select QIO.
Next, select the Flash Frequency every bit the "40Mhz"
Next, Select the Partitioning Scheme every bit the Huge APP.
Next, Select 115200 as the Upload Speed and Finally
Select the Programmer "AVR Isp"
Every bit you can meet Port: "COM3", this means that the Arduino board is connected with the Laptop through a USB Cable.
Click on the File Menu > Examples > ESP32 > Camera > CameraWebServer
Open the CameraWebServer Program.
Next, enter your SSID and password.
Select your Camera Model.
We are all set up, now we can click on the upload button.
Now the next step is to remove the wire that we used to short the IO0 pin and basis.
Click on the Serial monitor. Press the pushbutton available on the backside of the ESP32 Cam.
As you tin can come across the ESP32 Cam is unable to connect with the WiFi and seems like if the ESP32 Camera Module is resetting automatically, this is merely because the Arduino is not able to provide enough current to the ESP32 Cam Module. Sometimes y'all will run across,
[due east][photographic camera.c:1049] camera_probe(): detected camera non supported.
[e][camera.c:1249] esp_camera_init(): camera probe failed with error 0x20004
Now to fix these types of errors we can use an external 5V regulated Ability supply to ability upwards the ESP32 Module. So I am going to become 5V regulated ability supply lath based on the LM7805 Voltage regulator.
Connect the 5v pivot of the ESP32 Cam with the 5V pin on the ability supply, and brand sure the power supply ground is connected with the ESP32 Camera Module ground pin…Finally, power upwards the Power supply board.
As you tin see on the Serial Monitor, the ESP32 Photographic camera Module is connected with the WiFi and on the screen, I can see my local IP accost. Copy this link and Open the net browser and paste this link. Finally, Click on the Commencement Stream push button and that's it.
So, this is how easily Arduino Uno or Arduino Nano can be used to plan the ESP32-Cam Module. I hope you take learned something from this commodity. Don't forget to Subscribe to my Website and my YouTube aqueduct "Electronic Clinic".
