    • Video Button: This button lets you record videos from your camera attached with the raspberry pi.
    • Click Button: This button remains disabled unless the camera is connected properly and either one of the modes is selected i.e., photo or video. It lets you click photos in photo mode and lets you record videos in video mode.
    • Error Label: This error label pops up on the screen whenever the following scenario happens

  6. InternetThis App will help you to access the internet using PiTalk

    • APN: This entry takes in the APN of your Network Carrier
    • Port: This entry takes in the Communication Port assigned to it by the Raspberry Pi. The format is ttyxxx where x is the port assigned to it by the Raspberry Pi.
    • Note:It is recommended that the user connects the shield to the Pi along with mounting it over via GPIO pins and writing the port as ‘ttyUSBx’ where x is usually 3. This helps in uninterrupted AT communication of the shield with the GSM module via UART1 and internet is routed via UART2
    • Connect Button:This button connects the phone to the internet by taking the values from APN and Port. On successful connection, it will pop a label with the text ‘Connected’ when the user presses the Status button.
    • Disconnect Button: This button allows the user to disconnect from the internet (if connected previously).
