3.9 Camera
With Raspberry Pi, you can also use the camera to record various types of pictures or record movies. There are many kinds of cameras that can be connected to Raspberry Pi, and there are two types of camera that supports USB camera and supports CSI port of Raspberry Pi on a large scale.
3.9.1 USB Camera
The USB camera is easily available on the market. It is connected to the USB port and does not need any special installation work.
3.8.2 TFT-LCD
Raspberry Pi supports DSI (Digital Serial Interface) connection to support TFT-LCD display. You may purchase and use parts that support DSI port among the items sold on the market, and then it is not easy to obtain such a TFT-LCD in reality.
Below is the 7 “Touchscreen Monitor LCD with 800 x 480 display, officially sold by the Raspberry Pi Foundation. This allows you to display all information on the LCD like a tablet. This LCD connects to its own adapter board, and the adapter board is connected to the DSI port on the main board of Raspberry Pi by a ribbon cable, and is supplied with power through the GPIO port. The latest Raspbian operating system already integrates touchscreen driver that supports a 10-finger touch and on-screen keyboard, so you can operate the system without using a mouse or keyboard.
3.8 Video Output
3.8.1 HDMI Cable and HDMI Supporting Monitor
Raspberry Pi supports HDMI (High Definition Multimedia Interface) output as basic video output, and supports HDMI video port on board.
If you want to connect Raspberry Pi to an external display device using HDMI video port, you need HDMI Type-A cable. A video image of Raspberry Pi will be output through this cable.
3.7.2 Mouse
Raspberry Pi works well without a mouse connection. You may not need a mouse when using Raspberry Pi for a special purpose. You may also not need a mouse to connect to Raspberry Pi only via the network. However, it may be convenient to use a mouse when you need to purchase Raspberry Pi and install the operating system or install applications.
3.7 Input Device
3.7.1 Keyboard
Raspberry Pi works fine even if keyboard is not connected. Keyboard may not be necessary when you connect and use Raspberry Pi to a machine or facility or for other special purposes. Also, when connecting to Raspberry Pi only via network, you may not need a keyboard either. But when you need to purchase Raspberry Pi and install an operating system or install an application at first, you have to connect a keyboard.
3.6.4 Bluetooth Adapter
Bluetooth communication is usually used for mobile devices such as mobile phones to connect directly to a computer at a short distance, not through the network, to listen to music or videos, and to upload or download files. If you want to connect to a computer wirelessly using Bluetooth communication, both computers connected to each other must support Bluetooth function.
3.6.3 WI-FI Adapter
If you do not want to connect a specific computer to the network by cable and want to connect wirelessly, both the computer and the network access device must support the Wi-Fi function.

If you want to connect to the network using Wi-Fi in Raspberry Pi, you need to have a device that supports Wi-Fi network in Raspberry. The newest model, the Raspberry Pi 3 model B, provides Wi-Fi as standard, so you do not need to prepare a separate device, but if you want to use Wi-Fi on the previous model, you can buy Wi-Fi parts that support USB port . There are various types of USB Wi-Fi available on the market, so you can buy your favorite items.
3.6.2 LAN Cable
It is LAN cable that connects the computer to the network equipment by cable. To connect Raspberry Pi to a LAN network, one end of the LAN cable is to be connected to the Ethernet port and the other end to the LAN HUB.
3.6 Network Device
3.6.1 WAN Connection Device, LAN Hub and Router
If you want to connect your computer to a network and work with another computer, you need network access equipment. Commonly used networks include LAN networks and WAN networks.
A LAN network is a form in which a certain number of computers are connected to each other in a limited space, and a device used to connect to such a network is a LAN HUB. Through the LAN HUB, computers on the same network can exchange necessary data with each other.
