Now open any web browser in your smartphone or laptop and search the IP address displayed on OLED display. On powering the device to connect it to the Wi-Fi available in the network, it will show the IP address on the OLED display connected to it. Upload the source code esp32-webcam-server.ino into ESP32 as described above. The GPIO1 and GPIO 3 pins are free after uploading the program, so we can use them as I2C pins for connecting the OLED display. Only GPIO 1 and GPIO 3 are the free pins available, which can be used as serial pins for uploading the program in flash mode. The SD card module on ESP board uses GPIO 4, GPIO 12, and GPIO 13. The device can be powered using any regulated 5V DC adaptor, or a 6V battery, or a voltage regulator circuit. ![]() After uploading the source code esp32-webcam-server.ino into ES32 board, remove the board and use it in the circuit. The GPIO 0 pin is to be pulled to ground during uploading mode and reset button of the ESP32 needs to be pressed for first few seconds of uploading. The schematic for the programmer is shown in Fig. Therefore, to upload the sketch you need a USB-to-serial programmer. The ESP32 camera does not come with built-in USB-to-serial interface. 4: Schematic of ESP32 cam programming Software 3: Circuit diagram of ESP32 camera webserverįig. For programming ESP32 you need the USB-to-serial programmer shown in Fig. ![]() The circuit is built around voltage regulator LM1117, an OLED, and ESP32 cam. The circuit diagram for ESP32 camera webserver is shown in Fig. 2: Code snippet for setting Wi-Fi SSIDs list and passwords Bill of Material Next, get the IP address in the setup function and add the code line to display the IP address on the OLED display. Then add the OLED display library in that. To modify, you need to replace the Wi-Fi SSID network names in the list and their passwords with your own Wi-Fi network’s name and password.
