Beginning Arduino ov7670 Camera Development

Beginning Arduino ov7670 Camera Development

This book is a great investment for those interested in developing camera related projects for the Arduino. These camera applications can involve security, surveillance, photography, toys, robots, and drones. Specifically, this book covers the Omnivision ov7670 digital camera and its use with the Arduino microcontroller. This book takes an interactive hands on approach and shows the reader in a step by step guide how to use the ov7670 with the Arduino and an SD card reader/writer to take photos, save them to an SD card, and then to convert them to an easily viewable format. This book will save you many hours or even weeks of frustration in trying to get this camera to work correctly. This book also gives you the basic background on the Arduino and digital cameras in general so that you will be able to develop camera projects for cameras other than the ov7670.

Who this book is for:
1. Beginners to the Arduino interested in developing custom Arduino camera related projects that are suitable for photography, surveillance, security applications or for use with drones and robots.
2. High school and university students needing a quick start guide to using a low cost digital camera in their school projects.

Key Selling Points:
1. Provides an interactive "hands on example" based beginner's quick start guide to using the extremely popular Omnivision ov7670 camera with the Arduino including using the undocumented features and incorrectly documented features that are necessary to get the camera to operate correctly.
2. Provides a good starting point for Arduino based camera applications as diverse as image processing, photography, surveillance, and home security with professional quality reusable code for the reader to use in his or her own projects.
3. Covers the FIFO version of the ov7670 which is the preferred camera version for most camera projects.
