Learn how to take your first steps on a Raspberry Pi to start your path as a development maker

If you’re new to this whole Raspberry Pi environment , you probably don’t even have much of an idea where it’s plugged into power.

If that’s the case, right now we’ll give you a hand to make your first moves with a Raspberry Pi:

Assemble Raspberry Pi

The first step, of course, is to lay out the bits and pieces based on what we’re aiming for for the Pi.

If what you want is to build a computer, what you will need is:

  • Raspberry Pi board
  • Case
  • computer peripherals
  • heat sinks
  • micro SD card
  • Power cord
  • Cable HDMI
  • Cable Ethernet

All accessories are adapted to be integrated into the Raspberry Pi in a simple way. Once you get the board into place inside the frame, all you have to do is place the heat sinks over the main components: the CPU and the LAN chip. Once done, all that’s left to do is close and screw on the case. Then, it’s as simple as connecting each peripheral to its corresponding port: keyboard and mouse to USB, HDMI to monitor, ethernet cable to internet connection and finally the power supply.

Install an OS

For the Raspberry Pi to function as a PC, one basic requirement is needed: an operating system. Fortunately, for this purpose, the manufacturer’s official website offers us a tool that makes it much easier to install an OS. We are talking about NOOBS . You can find NOOBS completely free and installing it is very simple. You just have to download the ZIP file to your PC and unzip it.

Then you need to take a MicroSD card of at least 16GB, which is where we will install NOOBS. First of all, you need to format the SD in FAT32 format . You can do this through the native tool on your PC or through an additional program. After formatting, you just need to move the extracted files from the ZIP to the MicroSD card, and safely remove it from your PC. Once that’s done, all that’s left to do is insert it into your Raspberry Pi, boot it up, and follow the wizard’s instructions.

Configure OS

The installation of Raspberry Pi OS is quite fast and immediately after opening, you will pop up the guide window for the initial configurations that will show the IP of your equipment , and that you must write down and save for future uses.

The next thing it will ask for is to adjust the regional settings . In this section you only have to enter your country, your language and time zone. It will then ask for a username and password to replace the default ones, which are “pi” and “Raspberry ”, respectively. The last thing left to do is to choose a Wi-Fi connection just in case you are not connected to the internet via ethernet. If possible, prioritize the connection via cable, since it is more reliable and with higher quality.
