Raspberry Pi and a Bit About It

In this instructable i am going to explain what a raspberry pi is and a bit about it . Also what projects you can do on it.

Step 1: What Is a 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.

Step 2: RASPBERRY PI 2 MODEL B

The Raspberry Pi 2 Model B is the second generation Raspberry Pi. It replaced the original Raspberry Pi 1 Model B+ in February 2015. Compared to the Raspberry Pi 1 it has:

A 900MHz quad-core ARM Cortex-A7 CPU1GB RAMLike the (Pi 1) Model B+, it also has: 4 USB ports40 GPIO pinsFull HDMI portEthernet portCombined 3.5mm audio jack and composite videoCamera interface (CSI)Display interface (DSI)Micro SD card slotVideoCore IV 3D graphics coreBecause it has an ARMv7 processor, it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10 (see the blog for more information). The Raspberry Pi 2 has an identical form factor to the previous (Pi 1) Model B+ and has complete compatibility with Raspberry Pi 1. We recommend the Raspberry Pi 2 Model B for use in schools: it offers more flexibility for learners than the leaner (Pi 1) Model A+, which is more useful for embedded projects and projects which require very low power.

Step 3: RASPBERRY PI 1 MODEL B+

The Model B+ is the final revision of the original Raspberry Pi. It replaced the Model B in July 2014 and was superseded by the Raspberry Pi 2 Model B in February 2015. Compared to the Model B it has:

More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model A and B.More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.Better audio. The audio circuit incorporates a dedicated low-noise power supply.Neater form factor. We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes.The Model B+ is perfectly suitable for use in schools: it offers more flexibility for learners than the leaner Model A or A+, which are more useful for embedded projects and projects which require very low power, and has more USB ports than the Model B.

Step 4: RASPBERRY PI 1 MODEL A+

The Model A+ is the low-cost variant of the Raspberry Pi. It replaced the originalModel A in November 2014. Compared to the Model A it has:

More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model A and B.Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.Better audio. The audio circuit incorporates a dedicated low-noise power supply.Smaller, neater form factor. We’ve aligned the USB connector with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes. Model A+ is approximately 2cm shorter than the Model A.We recommend the Model A+ for for embedded projects and projects which require very low power, and which do not require Ethernet or multiple USB ports.

Step 5: RASPBERRY PI ZERO

The Raspberry Pi Zero is half the size of a Model A+, with twice the utility. A tiny Raspberry Pi that’s affordable enough for any project!

Step 6: RASPBERRY PI CASE

official Raspberry Pi case is finally here!

Step 7: RASPBERRY PI UNIVERSAL POWER SUPPLY

the official and recommended universal USB micro power supply for Raspberry Pi. We’ve tested this supply in all kinds of situations, and it’s as solid as a rock; it’ll keep feeding your Pi the steady 2A it needs for proper performance.

Step 8: CAMERA MODULE

Step 9: PI NOIR CAMERA

The Pi NoIR gives you everything the regular camera module offers, with one difference: it does not employ an infrared filter. (NoIR = No Infrared.) This means that pictures you take by daylight will look decidedly curious, but it gives you the ability to see in the dark with infrared lighting.

We bundle a little square of blue gel with the Pi NoIR, which you can use with the Pi NoIR to monitor the health of green plants. The Pi NoIR is very popular among wildlife hobbyists: with a few infra-red LEDs, you can monitor what nocturnal animals are doing in your garden without disturbing them. The camera works with all models of Raspberry Pi 1 and 2. It can be accessed through the MMAL and V4L APIs, and there are numerous third-party libraries built for it, including the Picamera Python library

Step 10: RASPBERRY PI USB WIFI DONGLE

Step 11: SENSE HAT

Step 12: RASPBERRY PI TOUCH DISPLAY

Step 13: COMPUTE MODULE DEVELOPMENT KIT

Step 14: COMPUTE MODULE

Compute Module is a Raspberry Pi in a more flexible form factor, intended for industrial application.

The compute module contains the guts of a Raspberry Pi (the BCM2835 processor and 512Mbyte of RAM) as well as a 4Gbyte eMMC Flash device (which is the equivalent of the SD card in the Pi). This is all integrated on to a small 67.6x30mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory). The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2835 SoC (which means that many more GPIOs and interfaces are available as compared to the Raspberry Pi), and designing the module into a custom system should be relatively straightforward as we’ve put all the tricky bits onto the module itself. The compute module is available for purchase in single units, or in batches of hundreds or thousands. To get started designing a PCB to use the module, we provide an open-source breakout board with a single module in an affordabledevelopment kit.

Step 15: 5 of the Best Raspberry Pi Projects

i am doing to show you 5 of the Best Raspberry Pi Projects

Step 16:

PROJECT #1 (EASY): DEDICATED MINECRAFT MACHINE

If you're sharing your PC with a Minecraft addict, you'll be keen to get their own dedicated computer. Enter Minecraft: Pi Edition, which requires a Pi and Raspbian SD card, and allows you to control your block world with Python script.pi.minecraft.net

Step 17: ​PROJECT #2 (CHALLENGING): PIBEACON

You'll need to add a Bluetooth 4.0 Low Energy (LE) USB dongle to make this work, but grab one of those and you can turn a Raspberry Pi into a functioning iBeacon that will transmit a message if it sports your phone in range. Follow the instructions at this link for a simple greeting and goodbye when you enter or leave your house.

Step 18: ​PROJECT #3 (CHALLENGING): SOLAR SMART METER

Everyone's going solar these days, and that's a good thing. But how are your panels performing? This neat hack takes the data from your off-grid electric system, feeds it through a Pi and beams it out via a basic web server to wherever you are over the net.bit.ly/pisolarmeter

Step 19: ​PROJECT #4 (FIENDISH): 3D SCANNER

For the truly ambitious, this 42-Pi 3D scanner can capture a complete 360 degree image of any object up to and including a human-sized one. It's not cheap - you'll also need 42 SD cards and cameras to go with the computers - but given you could probably program it for bullet-time cinematic filming too, it's worth it for the kudos alone.bit.ly/pi3dscanner

Step 20: ​PROJECT #5 (EASY): HOME SERVER

The classic 'My first Pi project' is to use one for streaming music and videos around a home network. It's even cheaper than a Chromecast and everything you need is simple to install. All you need is a USB drive of suitable size and it will play to almost any video
