Getting started with the ESP32 CAM WiFi Module Bluetooth with OV2640 Camera Module 2MP

This article is a quick getting started guide for the ESP32-CAM board. We’ll show you how to setup a video streaming web server with face recognition and detection in less than 5 minutes with Arduino IDE.

Hardware required

The ESP32-CAM doesn’t come with a USB connector, so you need a CP2102 Converter USB to Serial UART  to upload code through the U0R and U0T pins (serial pins).

Connecting the Hardware Using USB to Serial UART adapter

Plug your USB cable to FTDI Adapter

Connecting the Hardware Using ESP32-CAM Programming Adapter Board

Plug your usb to the ESP32-CAM-MB Micro USB Programmer.

Setting up the library and Board

Adding ESP32 platform to Arduino IDE

  1. Open the Preferences window from the Arduino IDE. Go to File -> Preferences.
  2. Paste the following line into the Additional Boards Manager URLs fieldhttps://dl.espressif.com/dl/package_esp32_index.json

  1. If you have entries in this field already then add the new line before them but separate them with a comma.
  2. Go to Tools -> Board -> Board Manager…

Type ESP32, point with mouse cursor on record line found (ESP32 by …) and click on Install button to install the new hardware libraries.

When installation done, close and open your Arduino IDE again. You will be able to find all the ESP32 boards in the Arduino IDE’s board selector.

Upload the sample sketch

In your Arduino IDE, go to File Examples ESP32 Camera and open the CameraWebServer example.

The following code should load.

Before uploading the code, you need to insert your network credentials in the following variables:

const char* ssid = "REPLACE_WITH_YOUR_SSID";
const char* password = "REPLACE_WITH_YOUR_PASSWORD";

Getting the IP address

After uploading the code, disconnect GPIO 0 from GND. Open the Serial Monitor at a baud rate of 115200. Press the ESP32-CAM on-board Reset button. The ESP32 IP address should be printed in the Serial Monitor.

RESULTS

Now, you can access your camera streaming server on your local network. Open a browser and type the ESP32-CAM IP address. Press the Start Streaming button to start video streaming. You also have the option to take photos by clicking the Get Still button. Unfortunately, this example doesn’t save the photos, but you can modify it to use the on board microSD Card to store the captured photos. There are also several camera settings that you can play with to adjust the image settings.

How to program ESP-32 cam using Arduino UNO board

In this article, I am going to describe how to program ESP32 cam module using arduino IDE & without FDTI & any other USB to ttl converter.

This low price development board has onboard 5volt to 3.3-volt voltage regulator chip, an ESP32 chip with Bluetooth(BLE), wifi, GPIO pins, 2MP camera & a big sized SMD led but unfortunately this cheap board has not any onboard programmer chip like other nodemcu board. Usually, we have to program it using FDTI or USB to TTL converter. IF you don’t have any USB to TTL converter & have an Arduino UNO then no need to waste money to buy this TTL converter.

You need to program in this method

  1. ESP32 cam
  2. Arduino UNO board
  3. Jumper wire
  4. Arduino IDE software

Connection ESP32 cam to Arduino UNO

  • Connect Arduino 5volt to esp 32 cam 5 volt.
  • Arduino GND to GND
  • Arduino RX to Cam board RX & TX to TX
  • Arduino reset pin to GND
  • ESP 32cam D0 to Gnd

Make sure the cam board DO is connected to gnd. It will enable esp 32 flash mode otherwise you can’t program it. after compleat, the programming remove D0 to gnd

Now open Arduino IDE on your PC, go to File > Preferences >

Now paste below link in the board manager URL

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

Now go to Tools > Board > Board manager > & search for ESP 32

You can see esp 32 board Download & install the latest version package

 

After complete, the installation go to Tools > Select port where arduino UNO is connected

  • Now go to board > select board > ESP32 ” Wrover Module”
  • Flash Mode > QIO
  • Flash Frequency > 40MHZ
  • Partition Scheme > Huge App (3mb No OTA)
  • Upload speed > 115200
  • Programmer > AVR ISP

Now it is ready for uploading sketch

You can test it Go to File > Example > ESP32 > Camera > Camera web server and upload the sample sketch
