What you need to have

Raspberry PI board

The current version of the board is Raspberri PI 4. They can have from 2 to 8 GB of RAM. For our projects 2GB is enough, but 4 or 8GB are much better if you want to use the board as a PC. Considering the prices, best price/value ratio will be either 4GB or 8GB.

It is possible to but Raspberry PI 3 cheaper. Llease attention for power supply and other accessories, they can be incompatible with version 3 of the board.

Here is Raspberry PI 4, 4GB version:

Electronic components

We can use these sensors to make some more fun projects with Raspberry PI.

Any computer display with HDMI plug in. I suspect you already have some kind of monitor at home. If you don’t then you check the optional part bellow. You can either buy a special touch screen for Raspberry PI, or any PC display with HDMI input.

You need a USB keyboard


Touchscreen monitor for Raspberry PI
It will be cool to have a touch screen for the raspberry PI, but we can do everything we need just connecting Raspberry PI to any HDMI monitor.
