MINI ARDUCAM MODULE CAMERA SHIELD - 2MP OV2640

Arducam Multi-camera adapter board for Arduino SPI Mini Camera

I have the above two components with me along with ARDUINO UNO R3. I want to stream video using these. ARDUCAM provides library for this.

ARDUCAM LIBRARY

ARDUCAM DATASHEET

When I have chosen example program ArduCAM_Shield_V2_Video_Streaming and tried uploading it to Arduino it showed no ArduCAM.h: No such file or directory.

enter image description here

I have downloaded the library and kept it in the libraries folder of ARDUINO.

Can someone help me out with this??

    did you install the library? Commented Sep 2, 2021 at 5:24
  • The error message in the image ("ArduCAM.h: no such file or directory") can only mean that the library hasn’t been installed correctly. Commented Sep 2, 2021 at 6:03
  • As Nick Gammon wrote: There is no way, that you are sending video with an Uno. Its just not up to the task Commented Sep 2, 2021 at 6:54

The Uno which you mention has 2 KB of RAM. 2 MP of data would be 2,000,000 x 3 bytes (red, green, and blue), in other words 6 MB.

The screenshot you showed seems to show that the library is designed to take a still photo and buffer it. As you might imagine, buffering 6 MB would take a while, especially as you can only fit 2 KB at a time.

You simply won't be streaming video using the Uno, so the error message is more-or-less irrelevant.

It might be relevant if you actually wanted to take single photos and send them.

In that case, you probably haven't installed the library properly.

  • Yeah, OK. I can't see the resolution but that looks like a whole series of stills at about 1 frame per second. I suppose you can call that "streaming video" if you want to have a security camera taking photos of a room in your house. I assumed by "video" you meant what most people would call video, namely around 24 FPS or more. Commented Sep 3, 2021 at 5:14
