Ever imagined? If your computer reduced to the size of a credit-card. If you could fit it into your things or objects and operate them through your computer? We are going to talk about a similar kind of concept here!
Raspberry pi is one of the projects under internet of things. To understand raspberry pi, first, we should have an idea about what Internet of Things is.
INTERNET OF THINGS: The Internet of Things (IoT) is the network of physical objects or things embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data.
The Internet of Things allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration between the physical world and computer-based systems that result in improved efficiency, accuracy and economic benefit.
Now, what is the term 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’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games. 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.
Also, the Raspberry Pi has the ability to interact with the outside world, and has been used in a wide array of digital maker projects, from music machines and parent detectors to weather stations and tweeting birdhouses with infra-red cameras.
From where did the idea of this device came?
Evolution of the idea: The idea came in 2006, due to the year-on-year decline in the number of students applying to read Computer Science. By 2008, the project started to look very realizable due to the success of mobile processors. Finally it came out in February 2012, that was 3 years ago.
What was the purpose of this project?
The main purpose of this project is to provide a fun environment for experimenting with programming and electronics, to make maintaining computers inexpensive, simple, open and easy to use in schools and making experimenting at home easier for children.
But, how is this device used?
To use raspberry pi as a computer, we would need some accessories that are: SD card (8 GB class 4 SD card – ideally pre-installed with NOOBS), display and connectivity cable (any HDMI/DVI input), keyboard and mouse (any standard USB keyboard and mouse will work with your raspberry pi), power supply (use a 5v micro USB power supply). Some additional things may also be used like, an internet connection, to update or download software, raspberry pi can be connected to the internet either via an Ethernet cable or a wifi adapter. Headphones, headphones or earphones with a 3.5mm jack will work with your raspberry pi.
Raspberry has launched 2 models A and B, lets Compare these models: comparing model A and model B of raspberry pi: First talking about model A: It has a 256 MB RAM, one USB port, but no Ethernet port, it has dimension of 8.6cm x 5.4cm x 1.5cm, and it costs $25. Now talking about model B: it consists 512 MB RAM, two USB ports, also one Ethernet port, and a little difference in dimension 8.6cm x 5.4cm x 1.7cm, it costs $35 that is 10$ more than that of model A.
What are the projects that are possible with Raspberry Pi?
A wide range of projects are possible with this small computer, a lot of inventions have been made using it. Here is a few existing projects of Raspberry Pi: Operating Coffee Maker through smart phone, A Gardening robot, Wireless extender, Home arcade box, Media centre for TV, Wireless control for stereo, Supercomputers, Whether station and so much more.
