So, you need to have Arduino IDE installed as well as the ESP32 add-on. In this example, we use Arduino IDE to program the ESP32-CAM board. Important: Make sure you have your Arduino IDE updated as well as the latest version of the ESP32 add-on. GPIO 4: Data 1 (also connected to the on-board LED)įollow the next steps to build a video streaming web server with the ESP32-CAM that you can access on your local network.The following pins are internally connected to the microSD card reader: When GPIO 0 is connected to GND, the ESP32 is in flashing mode. Additionally, GPIO 0 also plays an important role, since it determines whether the ESP32 is in flashing mode or not. You need these pins to upload code to your board. There are three GND pins and two pins for power: either 3.3V or 5V.
