Raspberry Pi with Pi Camera

Raspberry Pi with Pi Camera

In this module, I will describe on how to connect and use Pi Camera with Raspberry Pi.

Requirements:

1. Raspberry Pi .

2.  HDMI Cable connected to a TV/ Monitor.

3. A Raspberry Pi , Pi NoIR V2 Camera.

4. A  wired keyboard.

5. A wired USB mouse.

Connecting Pi camera with Raspberry Pi:

1. Follow the steps on my previous blog on how to connect a Raspberry Pi with Smart TV here .

2.  Open up your Raspberry Pi Camera module. Be aware that the camera can be damaged by static electricity. Before removing the camera from its grey anti-static bag, make sure you have discharged yourself by touching an earthed object (e.g. a radiator or PC Chassis).

3.  Install the Raspberry Pi Camera module by inserting the cable into the Raspberry Pi. The cable slots into the connector situated between the Ethernet and HDMI ports, with the silver connectors facing the HDMI port.

4. Boot up your Raspberry Pi.

5. From the prompt, run "sudo raspi-config". If the "camera" option is not listed, you will need to run a few commands to update your Raspberry Pi. Run "sudo apt-get update" and "sudo apt-get upgrade".

6. Run "sudo raspi-config" again - you should now see the "camera" option.

7.  Select Interfacing Options.

8. Select Camera

8.  Enable the Camera.

9.  Select “Finish” and reboot your Raspberry Pi.

Launching camera to take pictures:

Pictures can be taken via two ways:

      1.  By command  line interface "raspistill".(Needs no programming knowledge)

This is inbuilt command interface that can be used to take pictures wthout any prior knowledge of any programming language. To capture an image in jpeg format, type "raspistill -o image.jpg" at the prompt, where "image" is the name of your image.

      2.  By python script.

Steps:

      a.)  From the Pi Home screen launch the terminal.

      b.)  Run "cd Desktop/" and then "nano cameraexample.py"

      

      c.)  Type the below code into the editor and save it.

import time import picamera camera = picamera.PiCamera() camera.Capture('image.jpg')

Note: Follow the link https://wiki.gentoo.org/wiki/Nano/Basics_Guide if you are a newbie to nano editor.

  d. ) Save the file and from terminal Run "python cameraexample.py". You will now see a image file created with the name "image.jpg" on the Desktop. Open this file. This is your captured image.

Raspberry Pi with Samsung Smart TV

Raspberry Pi with Samsung Smart TV

In this blog, I will cover about steps to connect  Samsung Smart TV with Raspberry Pi .

Requirements:

 1. Samsung Smart TV with connected HDMI cable.

2.  Raspberry Pi module 

3.  A 5V micro USB power supply to power your Raspberry Pi. Be careful that whatever power supply you use outputs at least 5V; insufficient power will cause your Pi to behave in strange ways.

4. A USB wired keyboard.

5. A USB wired mouse.

Set Up:

1. Download the NOOBS software from here.
2. Extract the folder . It should look something like this:

        

       3. Format your SD Card with  SD Memory Card Formatter . (Note: You can  use any                 SD Card formatting tool or do it manually via Windows/Mac/Linux disk 

           management tool.)

      4. In the formatted SD Card, copy all the contents (as seen above) , in the SD Card.

      5. Insert the SD Card into the card slot on the Pi .

      6. Connect the HDMI cable (from the TV) to Pi HDMI slot.

      7. Switch on the TV and select Source as the HDMI cable connected. You might see a               "Unknown"next to the HDMI slot. This is your Raspberry Pi. Select this HDMI as        

          source.

      8. The complete Setup should look like this:
