Just bought a Raspberry Pi and don't know what to do with it? Well it's time that you grab that Pi, start working using this guide and stay tuned for more Raspberry Pi tutorials! This tutorial is for OS X and if you have a windows computer don't worry, I will post another tutorial for windows, so stay tuned !
Step 1: Stuff Needed to Bring Your Pi to Life
1. SD Card - Raspberry Pi doesn't have internal storage and stores everything on a SD card. Only buy class 10 SD Cards, it is denoted by a number in a half circle on the SD Card so make sure of it.
2. USB Mouse and Keyboard - You will need it to setup up your Pi and after that you can control in headless mode.
3. A Micro USB Charger - To supply power and make sure that it can at least supply 1 amp.
4. Case - Not necessary but it protects your Pi and makes it look good and I would recommend one.
5. Wifi adapter - You can also use the ethernet port but a long wire can be frustrating so I would recommend to go wireless and make sure it's compatible with Raspberry Pi's because not all work.
Step 2: Getting Raspbian on the SD Card (OS X Users)
1. Download the latest version of Raspbian from www.raspberrypi.org
2. Download ApplePi Baker from this link " http://www.tweaking4all.com/hardware/raspberry-pi/... "
3. Insert your sd card into your mac
4. Open Disk Utility from the launchpad and select your SD card from the devices list and click on erase.
5. Open ApplePi baker and select your SD card.
6. Click restore backup and select the Raspbian file that you downloaded from raspberry pi's website.
7. It will begin writing on the SD Card. It will take about 4 minutes.
8. After the writing process has finished, Eject the SD Card and you are done !!
Step 3: Starting the Pi
So finally to the fun part !!
1. Connect the mouse, keyboard, HDMI to your TV and the power supply and insert the SD card into your Pi.
2. It will start booting up and you will be greeted with the configuration menu.
3. Expand the file system by selecting on the first option
4. Select the third option and the second option from that. After this it will automatically boot up to the desktop.
5. Select the overclock option and set it to Pi 2
6. Select Finish and then click Reboot
7. It will boot up and you will get to the desktop
Step 4: Going Further
Once you have got to the desktop you can access python which is a great programming language and your control the General Purpose Input Output (GPIO) pins which are present on the Raspberry Pi, they are like the pins on the arduino but they have 3.3v logic level so be careful using them. There is also a version of minecraft included which is a very nice game but if you really want to play games on your Raspberry Pi then instead of installing Raspbian, install RetroPie it allows you to play retro games like mario, contra and tekken. I will post tutorial on how to do that and I will post another tutorial telling about the GPIO pins and how to control them so stay tuned and Enjoy !!
