And now for something different we have an interesting project by Arduino enthusiast Jordan Blanchard who has created an interesting version of a digital camera with an Arduino. This example uses a single infra-red photodiode to measure the brightness of a certain point - which is considered one pixel of an image.
The IR diode is then swept across two dimensions, using servos for positioning - stopping to take a reading for each new pixel. The data is send back to a PC running some processing code which assembles the data into a finished image. An example of the photo editing is shown in the following video:
You can learn more about this interesting device from the website (opens in Google Translate). And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
