First of all, We have to know about “what is Raspberry pi?” – The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing and to learn how to program in languages like Scratch and Python.
What We Will Make
The Raspberry Pi is a very small computer that can do lots of things. You simply plug it into a monitor and attach a keyboard and mouse like this,
What We Will Need
- A Raspberry Pi computer with an SD card or micro SD card
- A monitor with a cable (and, if needed, an HDMI adaptor)
- A USB keyboard and mouse
- A power supply
- Headphones or speakers (optional)
- An ethernet cable (optional)
How Raspberry Pi Looks Like
You are going to take a first look at Raspberry Pi! You should have a Raspberry Pi computer in front of you for this. The computer shouldn’t be connected to anything yet.
- Look at your Raspberry Pi. Can you find all the things labeled on the diagram?
- SD card slot — you can slot the SD card in here. This is where the operating system software and your files are stored.
- Ethernet port — this is used to connect Raspberry Pi to a network with a cable. Raspberry Pi can also connect to a network via wireless LAN.
- USB ports — these are used to connect a mouse and keyboard. You can also connect other components, such as a USB drive.
- HDMI port — this is where you connect the monitor (or projector) that you are using to display the output from the Raspberry Pi. If your monitor has speakers, you can also use them to hear the sound.
- Micro USB power connector — this is where you connect a power supply. You should always do this last after you have connected all your other components.
- GPIO ports — these allow you to connect electronic components such as LEDs and buttons to Raspberry Pi.
- Audio jack — you can connect headphones or speakers here.
Connect Your Raspberry Pi
Check the slot on the underside of your Raspberry Pi to see whether an SD card is inside. If no SD card is there, then insert an SD card with Raspbian installed.
Find the USB connector end of your mouse’s cable, and connect the mouse to a USB port on your Raspberry Pi.
- Connect the keyboard in the same way.
- Look at the HDMI port(s) on your Raspberry Pi — notice that they have a flat side on top.
- Use a cable to connect the screen to the Raspberry Pi’s HDMI port — use an adapter if necessary.
For Raspberry Pi 4: Connect your screen to the first of Raspberry Pi 4’s HDMI ports, labeled HDMI0.
For Raspberry Pi 1,2,3: Connect your screen to the single HDMI port.
If you want to connect the Pi to the internet via Ethernet, use an Ethernet cable to connect the Ethernet port on the Raspberry Pi to an Ethernet socket on the wall or on your internet router. You don’t need to do this if you want to use wireless connectivity, or if you don’t want to connect to the internet.
After that, you should see a red light on your Raspberry Pi and raspberries on the monitor. Your Raspberry Pi then turns into a graphical desktop.
Time to Finish The Setup
So, This all about the Raspberry pi.
