Follow the steps below to connect your Bluetooth Keyboard or Mouse to your Raspberry Pi.
I’m using a Logitech K380 on the examples below since that is my Bluetooth keyboard. But you can follow the same steps if you are using a different Bluetooth keyboard or device, such as a Bluetooth mouse.
The first time I used a Raspberry Pi years ago, I got frustrated that I could not connect to the WiFi Network. So I tested on the text editor if I am typing the correct password. As it turns out, pressing the backslash (\) on the keyboard will type the hashtag symbol (#), and if I press Shift + 2 will type double-quotes (") instead of At sign (@).
The reason for the incorrect characters being typed is by default the Raspberry Pi is set to use a UK-based keyboard layout. To correct this, we need to reconfigure the keyboard layout to the ones we are using.
In my case, I am using a US-based keyboard layout. In the tutorial below that is what I am going to use. You can select the keyboard layout that you are using.
There are several ways to update the Keyboard Layout in a Raspberry Pi, you may choose which one you prefer on the list below.
Depending on the screen size or the usage of the Raspberry Pi, I usually tweak the font size and icon size.
If I am teaching or recording videos, I want the icon and font size to be large. If I am blogging, then I want them to be medium size. If I am using a small resolution screen then I want to change the icon and font size to a smaller proportion.
Luckily, Raspberry Pi has a Set Defaults icon for different screen sizes which makes it quick for me to change the sizes.
To change the system icon and font size of the Raspberry Pi head over to Appearance Settings and tweak the configuration there.
If you need guidance or instructions on how to navigate the settings then follow the tutorial below.
A headless setup is when your Raspberry Pi is turned on without a monitor.
The display is not needed usually, especially if your access is only via SSH. The issue would be if you connect via VNC Viewer, the display will look like this.
The icons are too big but the screen is too small.
What’s happening here is that Raspberry Pi will use a very small screen resolution when it is not connected to a monitor. So when you connect via VNC Viewer, VNC will get the same small screen resolution.
To solve this, we need to change the default headless screen resolution of the Raspberry Pi. You can follow the instructions below to set this.

Now when you want to use an SD Card back to like using it on your Android Phone or camera, you just cannot use it by simply inserting it on the SD Card slot and turning on your gadget. You have to properly format the SD Card.
Note: If this method does not work for you, I will be writing another method for Windows, Mac and Linux systems in the future.
If you format separately the two drives (E: and F:), you will end up with two drives instead of one that has the full capacity of the SD Card.
I have always used Synergy when using multiple computers since I do not want to use a lot of hardware (mouse and keyboard) to control all my unit. When I first received a Raspberry Pi the first thing I did was make Synergy work.
Here is the configuration that I use when working with Raspberry Pi.
Client – Raspberry Pi (to be controlled)
Server – Laptop where the mouse and keyboard will be used (Windows/Mac)
1. Installing Synergy on Raspbian
Open the terminal and run the code below.
sudo apt-get install synergy
This will install Synergy on the Raspberry Pi along with its dependencies.
I just bought the official casing of Raspberry Pi and I am very happy with it.
I always bringing my Raspberry Pi 3 inside its box for extra protection from being crushed inside my bag. Then I realized that sometimes I would like to use my Raspberry Pi inside coffee shops or in public places where I can work.
Having a bare Raspberry Pi board would make people doubt what you are doing since you are have an electronic board with you. Embarrassing if people would glance at you thinking that you are doing something bad. Seriously bad if a guard or police would approach you. These are the reason why I bought my case.
