You can do this (most simply) by going to ‘Preferences->Raspberry Pi Configuration’ and selecting the ‘interfaces’ tab, and finally clicking ‘enable’ next to the camera option. First, you need to make sure your Raspberry Pi is up-to-date by typing the following commands: sudo apt -get update sudo apt -get upgrade These commands will update the installed packages on your Raspberry Pi to the latest versions. The starting point for getting the picamera working is to ensure that it is enabled in the Raspberry Pi Configuration. The best ‘getting started’ tutorials are listed below:

There are numerous ‘getting started with the picamera’ tutorials out there, and so I will merely mention a few recommended tutorials and briefly explain how to prepare the picamera for use with the Pi and Python. Keeping the black strip on the same side as the white casing is required for both the picamera and Pi Zero slots. Notice the black strip facing upward when wiring the ribbon to the slot. If the wiring is still unclear, see the image below. The silver tracks should always be in contact with the tracks its being connected to - be wary of mistaking this, as the tracks on the ribbon can be damaged if the ribbon is inserted incorrectly into the Pi or picamera slots. For the RPi Zero, the ribbon cable tapers to a thinner profile, which is where the Pi should be wired. Wiring the picamera to the RPi is quite simple - both the picamera and the Pi have ribbon inputs where the thick ribbon cable is inputted. Raspberry Pi Zero W with Cables - $22.80 I don’t imagine there are any differences in application between the two, so I will proceed under the assumption that either suffices. The other picamera should work just as well, the V2, which boasts 8MP, but the same video quality. Unmount the rootfs partition if it is mounted (a key. There are two picameras available, however, I will be using the older and cheaper version, V1.3, which is a 5MP camera that can record HD video. Select your external microSD card from the pull down menu in the upper right corner of the gparted window. There are only two essential parts needed for this tutorial: the Raspberry Pi and the picamera.
