50 of the most important Raspberry Pi Sensors and Components

50 Raspberry Pi Sensors and Components.

One of the many advantages of the Raspberry Pi is that it is possible to connect almost all standard Arduino and Raspberry Pi sensors and components to the various GPIOs. Moreover you can evaluate and / or process the values with programs and other software. This accessory can be used in projects such as Smart Home (home automation), robot kits or weather stations, etc.

This article describes and summarizes over 50 of the most important sensors and components for Raspberry Pi’s as well as Arduinos and provides you with a full Raspberry Pi sensor list.

How to get Google Chrome for the Raspberry Pi

Google Chrome is one of the fastest and most widely used web browsers for desktop computers. Due to some statistics Chrome is used on more than half of all PC’s of the world. Since it is a opensource project, you can get also Chrome for Raspberry Pi’s.

In this tutorial I will show how to install Chromium on a Raspberry Pi.

Top 10 Raspberry Pi 2 Cases (with fan, screen, …)

Raspberry Pi 2 official case

All Raspberry Pi models are delivered without a case. But to protect your Pi it is recommended to use one and additionally it is nice to look at. There are so many really nice cases with fans or integrated touchscreens. You might ask which is the best Raspberry Pi case and which are most useful for your Pi.

In this article you will get the answer! I will show you my top 10 Raspberry Pi cases for model 2B and B+ which are way more than just a box and give your Pi a personal style.

How to setup a Raspberry Pi FTP Server – Webserver Installation

Raspberry Pi FTP Server Installation

For uploading files on a Raspberry Pi you should install a FTP server. Such a server is very useful if you use your Pi as a web server or even if you want to have a network storage, which can also be accessed outside of your network if an DNS server is installed.

However this tutorial is not only for web server but can also be used for easy file transfer between Raspberry Pi and your PC.

How to establish a Raspberry Pi Remote Desktop Connection

Similar to TeamViewer a remote desktop connection enables remote access to another computer. This has the advantage that you don’t need two monitors or have to switch between two systems.

Although the Raspberry Pi can be controlled almost exclusively via console, but some programs are to be controlled only by a GUI. On all Windows systems a program for remote access is already installed and therefore it requires no additional software. And even on Mac OS or other Linux distributions it is very easy to connect to the Pi.

Raspberry Pi Stepper Motor Control with L293D / ULN2003A

Stepper motors are ideal for applications where it is necessary to know the angle of rotation, for example in robotics. Unlike a normal motor, stepper motors can control the steps individually and can therefore detect the exact position.
For easy controlling such a motor, a driver IC like the L293D or the ULN2003 are needed. The use of both drivers is shown in this tutorial.

Using a Raspberry Pi distance sensor (ultrasonic sensor HC-SR04)

For many (outdoor) projects a distance measurement is necessary or advantageous. These small modules are available starting at 1-2 bucks and can measure the distance up to 4-5 meters by ultrasound and are suprisingly accurate. This tutorial shows the connection and control.

Let Raspberry Pi’s communicate with each other per 433MHz wireless signals

Maybe some of you thought about how to let some RaspberryPi’s communicate with each other wirelessly. For this purpose small 433MHz modules are ideal, which are already available for a few bucks.

Therefore in this tutorial I want to show how two (or more) RaspberryPi’s can “talk” with each other. But do not worry, if you have only one Raspberry Pi, you can do it also.

Installing WiringPi (and pin allocation) – Raspberry Pi

WiringPi is a library that is used by many applications on the Raspberry but is not available by default. Especially many examples from the Arduino (C ++ code) can be performed easily on the RaspberryPi. To do so, this valuable library was written.
