There are also useful accessories you may consider get like an HDMI cable to connect a monitor, and a Raspberry Pi case to protect your board.
You can get a microSD card with the operating system preloaded or install the operating system yourself. You need a microSD card to store your files and the Pi’s operating system. The Pi doesn’t have an hard drive, so everything you do on your Pi is saved on the microSD card, even the operating system. MicroSD card: you need at least one with 8GB, class 10.Power supply: you need a power adapter that provides 2.5A 5V.Without these accessories your Raspberry Pi is useless. There are a lot of accessories for the Raspberry Pi, but you need at least a microSD card and a power supply. You need several accessories to get started. When you buy a Raspberry Pi board, you only get a bare electronic board that doesn’t do much on its own. GPIOs (general purpose input output pins): connect devices to interact with the outside world like sensors and outputs like LEDs and motors.
The Raspberry Pi board has one special feature that normal computers don’t: General Purpose Input Output (GPIOs) Pins. The figure below shows the Raspberry Pi 3 set as a desktop computer. You can do most things you do with a regular computer like web browsing, document editing, playing games, coding and much more. It’s the perfect solution for tinkerers! In some way, you can look at the Raspberry Pi as a normal computer, it has a processor, RAM, USB ports to plug a keyboard and a mouse, HDMI port to plug a TV or monitor, and you can even connect it to the internet. The Raspberry Pi costs around $35 is hackable and small. “ The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.” From Wikipedia.
Finally, we’ll also show you how to get started by installing the operating system, and what accessories do you need. You’ll explore its features and see what sets it apart from a normal computer. You’ll see what is the Raspberry Pi and what can you use it for. This post is an introduction to the Raspberry Pi.
