Raspberry Pi Camera Module Review and Tutorial Guide - Working with the camera


By: | Guides | Posted: Jul 22, 2013 9:13 pm

Working with the camera

 

Now that the Raspberry Pi is finished rebooting, you can login and we can begin taking some video and snapshots using basic commands. Later in this article I will show you how to string together some of these commands to create a time-lapse photography setup that is quite energy efficient and should provide 12 hours of use.
