Hey guys,

Do you want to make your own Robot, Your own Home Theatre, IOT based home and etc.

But, how can we do this.

So, let's find the answers..

     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.

Raspberry pi circuit

     As you can see that there are many ports like SD card, USB power port, Ethernet for WiFi, USB to connect with Computer LCD, Audio and video plug and etc.

 SD Card port 

    In SD card port we can insert memory card or SD card because there is no hard disk for storage.

In SD card we can install an operating system and use it.

It must be of class of 10 and minimum 8 GB.

Network

In network port we can insert an Ethernet cable to get internet services.

There is also a Bluetooth and WiFi connector.

Camera

There is also a camera port but there is no inbuilt camera that is why we have to insert external camera for security and many other.

We can use it as PIR Sensor or CCTV camera. 

              PIR Sensor

HDMI (Output)

It gives the final output.

As we connect the CPU with our desktop exactly here we have to use HDMI cable to connect the Raspberry pi and the display for output.

If you have LED or LCD then you can use this HDMI cable .If there is a HDMI port in your desktop already then you can also use it.

If the desktop has only VGA(VideoGraphic Array) port  then this type of connector can be used.

In this type of cable you have to use a VGA cable to connect this and the desktop.

Power

For giving power to the circuit you can use the simple  mobile charger but not high voltage charger.

We can also connect it with our laptop.

• In USB ports we can connect our keyboard and mouse.

History

This ultra-tiny computer was designed to be small and cheap so that
 schools could easily afford them in order to teach students about computers in the classroom.

The main goal was to release computers around $30 This should help schools to teach computing and allow students to be interested by jobs in this field of activity.The foundation introduces Scratch as a first programming language for kids.

Applications

Web server

Because it uses very little power, the Pi can stay on 24/7 without requiring a cooling fan or jacking up your electric bill. It's also more than fast enough to serve web pages, either over the internet or just within your local network.

Laptop

Believe it or not, you can build a laptop that uses a Raspberry Pi as the brain. Available for $285, the pi-top is a bright-green notebook with a 14-inch, 1080px screen and up to 8 hours of battery life. It uses a Raspberry Pi 3B or 3B+ for all of its processing and comes with pi-top OS, a version of Linux that has lots of educational software built in to help kids learn about programming.

Kid’s first computer

One of our favorite children's gadgets, the Kano Computer Kit, comes with all the materials that kids as young as 6 can use to build their own Raspberry Pi-powered PC. 

Robot Car

Several awesome kits let you make a robotic vehicle with a Raspberry Pi as the brain. Sun Founder's $119 Raspberry Pi Smart Robot Kit gives you all the parts you need (except the Pi) to build a four-wheel car with distance sensors, light sensors and motors. Available for $109, the smaller GoPiGo3 has three wheels and a distance sensor.

Portable (small) PC

Sometimes it is complex to carry a laptop or a PC due to their large size.
So, here is a small and good PC made by Raspberry pi  in small size which is able to do all your work.

Some others applications :-

• Home Theatre PC
• WiFi extender
• Alexa speaker
• Security Camera
• Automatic Plant Waterer
• In IOT
• Robot
