INTRODUCTION TO "RASPBERRY-Pi"
What is Raspberry-Pi?
Shown below is an image of Raspberry pi v2
What is the raspberry-pi used for?
Well this question does not have a single answer. The Raspberry Pi is a wonderful little computer that fits in the palm of your hand, yet packs enough power to run your home media center, a VPN, 3d printer, robots and much more. The possibilities are endless with GPIO(general purpose input/output pin). Connect different sensors to your pi with the gpio pin inlet that are present in it and built your own home automation system or security system and much more.......
According to the Raspberry Pi Foundation, over 5 million Raspberry Pis have been sold before February 2015, making it the best-selling British computer. By 9 September 2016 they had sold 10 million.
Operating Systems supported:
Raspberry Pi runs on official operating system, version of Debian Linux called "Raspbian". It uses a Fedora distribution of Linux as a default operating system. There is also a version of windows called windows "IOT" that is designed for raspberry pi and other boards like banana-pi.
Other operating system supported:
1.Ubuntu mate
2. Risc os
3. NOOBS
3. PINET
4. OSMC.
HARDWARE:
All models feature a Broadcom system on a chip (SoC), which includes an ARM compatible central processing unit (CPU) and an on-chip graphics processing unit (GPU, a VideoCore IV). CPU speed ranges from 700 MHz to 1.2 GHz for the Pi 3 and on board memory range from 256 MB to 1 GB RAM. Secure Digital (SD) cards are used to store the operating system and program memory in either the SDHC or MicroSDHC sizes. Most boards have between one and four USB slots, HDMI and composite video output, and a 3.5 mm phone jack for audio. Lower level output is provided by a number of GPIO pins which support common protocols like I²C. The B-models have an 8P8C Ethernet port and the Pi 3 and Pi Zero W have on board Wi-Fi 802.11n and Bluetooth.
Here's the outlook

SPECS:
The latest raspberry pi i.e model 3 includes built in 802.11n WiFi, Bluetooth 4.0, and a quad-core 64-bit ARM Cortex A53 running at 1.2 GHz. It’s a usable desktop computer. Available now at the usual Pi retailers for Rs 2400/-.
The headlining feature of the Pi 3 is the built-in WiFi and Bluetooth, but it doesn’t stop there. Here’s the complete specs for the Pi 3:
- SoC: Broadcom BCM2837 (roughly 50% faster than the Pi 2)
- CPU: 1.2 GHZ quad-core ARM Cortex A53 (ARMv8 Instruction Set)
- GPU: Broadcom VideoCore IV @ 400 MHz
- Memory: 1 GB LPDDR2-900 SDRAM
- USB ports: 4
- Network: 10/100 MBPS Ethernet, 802.11n Wireless LAN, Bluetooth 4.0
How to get your pi up and running:
To get your pi up and running you need an SD card, it will act as secondary storage device or a hard disk for the pi. Flash the sd card with the latest version of the "RASPBIAN" O.S, visit the official website to download the latest version of the OS. Then you need a mouse and keyboard that can be connected to the usb ports of the pi to control it. Finally you need a monitor to act as a display unit for the pi, or you can also connect your pi to your LAN and access it remotely from your desktop or laptop.
TOP PROJECTS:
Portaberry Pi
Turning the Raspberry Pi into a gaming machine is a classic use case for the mini computer emulators for the legally gray win!—but Portaberry Pi is one of the nicer set-ups. It includes a Raspberry Pi Model B, a 4.5-inch TFT display, a 3D-printed case, and various components to construct a boxy handheld retro gaming device. Check out the finished project on YouTube with the device running Super Mario World for Super Nintendo.
Magic mirror
Developer Michael Teeuw came up with a neat idea for a home project: Create a high-tech mirror that shows you the weather, time, and the day’s headlines while you’re getting ready for the day.
For his project Teeuw took a one-way mirror, attached a display and Raspberry Pi to the back, and put it all together in a custom-made case. It’s a killer concept, and his “magic mirror” inspired others to create their own versions. You can find full details on how he built the mirror on Teeuw’s blog, along with another post showing off other mirrors from around the world.
Its capabilities are extensively used for built robots that can not only move or pick up things but can also do natural language processing or NLP and respond to you just like a human.
Semi-autonomous quad-copter
This is a more expensive and mechanically intense project, but what’s more rewarding than building your own Raspberry Pi-powered miniature vehicle?
UK-based Pi enthusiast Andy Baker has a breakdown of how he built his own semi-autonomous quad-copter that comes programmed with its own flight plan. There are quite a few articles to read through, but this one is probably your best starting point. Also be sure to check out the new quad-copter project that he just started in February.
and many more. Possibilities are endless with Pi!!!!.
Thanks for reading please subscribe!!! and stay tuned for the next post on Internet of Things(IOT).
