## CircuitPython Webcam with OV2640 and Adafruit IO

Info: 

With a WiFi-enabled board like the Espressif Kaluga, you can upload your image data to [Adafruit IO](https://io.adafruit.com/). We made sure that this example works with the free version, so you can try it out even if you haven't upgraded to an IO+ subscription yet. New to Adafruit IO? [Start with this guide](https://learn.adafruit.com/adafruit-io-basics-airlift/circuitpython) to learn the basics.

## Set up IO Feed

New to Adafruit IO? Check out the [Adafruit IO Basics guide](https://learn.adafruit.com/adafruit-io-basics-feeds/overview), or [detailed instructions on creating a feed.](https://learn.adafruit.com/adafruit-io-basics-feeds/creating-a-feed)

## Set up the IO Feed

Create a feed called "image" and then set "Feed History" to "OFF". This allows storage of data up to 100kB, which is plenty to upload JPEGs at 640x480 resolution. (You can choose another feed name but you'll need to **make sure** that Adafruit IO's "key" for the feed matches what you use in your CircuitPython program!)

## Set up the IO Dashboard

Create a new dashboard. Click the gear icon and then "Create New Block". Choose the camera icon ("image") and then select your feed named "image". Enter a block title if you like, and click "Create Block".

## CircuitPython Code

## Secrets File Setup for Adafruit IO

If you don't have a **secrets.py** file in your **CIRCUITPY** drive yet, create one and add the information about your wifi connection.

Then, add the following code to your **secrets.py**  file, **replacing** `_your_adafruit_io_username` **with your Adafruit IO username.**

Then, **replace**  `_your_big_huge_super_long_aio_key_` **with your Adafruit IO Active Key**.

```auto
secrets = {
    'ssid' : '_your_wifi_ssid_',
    'password' : '_your_wifi_password_',
    'aio_username' : '_your_adafruit_io_username_',
    'aio_key' : '_your_big_huge_super_long_aio_key_',
}
```

Make sure you **save this file** before proceeding as **secrets.py** in the root directory of your board **CIRCUITPY** drive **.**

## Upload the code

Click "Download Project Bundle" below and unzip it on your Espressif Kaluga's **CIRCUITPY** drive. It will automatically start the code and upload a 640x480 JPEG to Adafruit IO every 3 seconds or so. If you run into trouble, open up the REPL to look for clues. Carefully double-check your WIFI and Adafruit IO login information, and that you properly created & configured the Adafruit IO Feed and Dashboard.

https://github.com/adafruit/Adafruit_CircuitPython_OV2640/blob/main/examples/ov2640_aio_kaluga1_3.py

## Watch the camera feed

Just open up the Dashboard on Adafruit IO. The image in your browser will update shortly after each new image is uploaded from the ESP32-S2.

## Take it Further

Here are some improvements and changes you might want to make to the code:

- WiFi camera: Add a button to take a photo, and an LCD to act as a viewfinder.
- Add a button to the Adafruit IO Dashboard that signals the camera to upload a fresh photo
- Video Doorbell: Add a button to take a photo, and send you a notification on your phone (requires an IFTTT account)
- Use a PC or Raspberry Pi to download & analyze the images
