What is the Raspberry Pi?
The Raspberry Pi is a miniature computer that is ideal for handicrafts or home automation. Thanks to its controllable IO (input-output) pins, sensors and other hardware can be read out and controlled very easily. Because of this and its low price, it is also a very popular way to get started with (hardware-related) programming for beginners, children and those interested.
In the meantime, the Raspberry Pi has been sold millions of times and there is a ready-made solution for almost every application, or a way to achieve your dream project. This page deals with all topics related to the Raspberry Pi. This includes simple tutorials on the use of sensors, pure help on programming topics, to complex Raspberry Pi tutorial series in the field of home automation, robotics and many more. You can simply browse in the menu and on the page or leave a comment. Since new Raspberry Pi instructions and tutorials appear regularly, it is definitely worth activating the newsletter.
Anyone who has dealt with image processing in relation to the Raspberry Pi will sooner or later come across the OpenCV library. It provides many very useful features such as face recognition, the creation of depth maps (stereo vision, optical flow), text recognition or even for machine learning. In addition,…
Often you want to control modules with a higher voltage with the Raspberry Pi. For this purpose, relays can be used on the Raspberry Pi: The relay “switch” is utilized by means of a low-voltage pulse. Since the Pi only tolerates a maximum of 5V (the GPIOs even only 3.3V)…
There are some infrared distance sensors from the manufacturer Sharp, which can be operated very simply with the Raspberry Pi. There are different distance meters, which cover different distance ranges. These modules work similarly to laser distance meters, but with infrared light. There, bundled light is emitted by a transmitter…
The official Raspberry Pi camera module has the advantage that it doesn’t need any USB ports or GPIO pins and can be used directly via the CSI port. It is available with and without an infrared filter, which for example can be of advantage when shooting at night. This tutorial…
Often you want to be able to control (household) devices with a higher voltage with the Pi. Raspberry Pi wireless-controlled sockets are ideal for this because they are very easy to control and you do not have to interfere with the circuit. For that and many other projects, there are…
In addition to stepper motors, there are also small and cheap servo motors. The control of Raspberry Pi servo motors is very simple and thanks to the small size and weight they are used in many areas. Unlike stepper motors, servomotors can be controlled with a single GPIO. In this tutorial,…
While every smartphone has GPS, the Pi can also be converted into a GPS receiver with a cheap Raspberry Pi GPS module. In many outdoor applications, especially those that move (Car-PC, weather balloon, etc.), the exact position is a big advantage. Mobility is achieved with a battery pack or a…
Due to its design, the PIR motion sensor module is very easy to use because it already has the components installed. Raspberry Pi motion detectors in home automation and/or outdoor applications (as a classic outdoor motion detector) are easier than ever to implement. I will show the commissioning in this…
Whoever is aiming for home automation will sooner or later certainly think about the wireless operation. The 433Mhz frequency is ideal for this because there are many cheap transmitters and receivers as well as a wide range of available libraries and scripts. In this tutorial, I want to show how…
Siri, Amazon Echo and “S Voice” are all voice recognition programs designed to make life easier. Even a Raspberry Pi voice control can be easily built by yourself. Because such a speech recognition is of course very beneficial for home automation. In this tutorial, I’ll show you how to digitize…
