Configure and read out the Raspberry Pi gas sensor (MQ-X)

Felix - 17. March 2017

Sensors are necessary to detect the components of the air. These are used e.g. in smoke detectors. However, instructions for using these gas sensors at the Raspberry Pi are rare, which is why in this tutorial the general use of such MQ modules at the Raspberry Pi is shown. Thus, e.g. smoke detectors or air […]

Top 10 Raspberry Pi 3 Cases (with fan, screen, …)

Felix - 22. February 2016

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 […]

How to setup a Raspberry Pi FTP Server – Webserver Installation

Felix - 9. February 2016

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 […]

How to establish a Raspberry Pi Remote Desktop Connection

Felix - 8. February 2016

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 […]

Raspberry Pi Remote Access by using SSH and Putty

Felix - 5. February 2016

After setting up your Raspberry Pi you probably don’t want to use your keyboard and mouse. That’s where a remote connection helps: You can have remote access to your Raspberry Pi through SSH from every other computer which is in the same network as your Pi. In this Tutorial you will learn how to use […]

50 of the most important Raspberry Pi Sensors and Components

Felix - 22. January 2016

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 […]

Measuring Rotation and acceleration with the Raspberry Pi

Felix - 30. November 2015

Acceleration and rotation sensors are most known from smartphones. The rotation of the device can be detected and can be addressed directly. With the Raspberry Pi and a Gyroscope / Accelerator sensor it is possible to measure the rotation as well as the acceleration of the 3 axes. In this tutorial I show how to […]

Raspberry Pi Stepper Motor Control with L293D / ULN2003A

Felix - 14. November 2015

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. […]

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

Felix - 11. November 2015

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

Felix - 26. October 2015

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 […]
