Hi !

Let’s start a series of posts using an ESP32 CAM board. I had this one from Amazon Canada.

Wobekuy ESP32-CAM-MB WiFi Development Board OV2640 Camera Module -USB Interface CH340G USB to Serial Port

I choosed this one, because it will avoid me the pain of wiring.

So, 1st test, let’s turn the Flash ON and then OFF.

Let’s start creating a new PlatformIO project, and selecting the right board: AI Thinker ESP-32CAM

Once the project is created our ini file contains the following information:

; PlatformIO Project Configuration File
;
; Build options: build flags, source filter
; Upload options: custom upload port, speed and extra flags
; Library options: dependencies, extra library storages
; Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:esp32cam]
platform = espressif32
board = esp32cam
framework = arduino

And now let’s add some code to make the flash work. And, my only note here is that the Pin is 4.

Full project working demo

Happy coding!

Greetings
