Preparing Hardware

Let’s start from the very beginning, as I did not use my Raspberry Pi for quite a long time.

We will need:

Raspberry Pi board (or other IoT-oriented platform).

SD or microSD card (depending on the platform).

5V/1A via micro-USB.

LAN cable, which provides the Internet connection.

HDMI display, RCA display, or UART port (to enable SSH).

The very first step is downloading Raspbian. I’ve chosen the Lite version, as I’m going to use SSH instead of display.

Things have changed since the last time I did it: now there is a great burning software called Etcher, which works perfectly, and has a stunning design.

After the image burning was completed, I inserted the SD card into my Pi, plugged the LAN and power cables in, and after a while, my router registered the new device.

Great! Let’s go on and SSH into it.

No way! SSH is disabled by default

Security is OK, I like it, but this makes things a bit harder. I’ll use UART-USB adapter to access the shell and enable SSH…

Using a display instead of UART makes it much easier.

After rebooting, I’m finally in.

First things first, let’s update:

sudo apt update && sudo apt upgrade -y

Now let’s connect this fresh device to the Cloud.
