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.
Mainly in mobile applications, a static power supply is not always guaranteed or there is no outlet nearby. A Raspberry Pi battery pack or a mobile power supply is beneficial in many cases. In this tutorial, I want to show one way to operate the Pi using normal AA batteries…
For some applications, such as games, a joystick can be useful or be even necessary. Since these usually work purely analogously, the signal has to be converted, which we do with the MCP3008 chip. Connecting and reading a joystick is shown in this tutorial.
A Raspberry Pi surveillance camera can be a cheap alternative to common variants like IP cameras. An ideal Raspberry Pi camera module represents normal webcams that can be used as well, connected via USB. This tutorial shows how to use a webcam with the help of the software fswebcam. In…
It continues with the second part and the actual Traffic Light Circuit. Let’s take a look at the various Traffic Light Signals on Wikipedia. We want to recreate them at the push of a Button.
This tutorial is about a simple Traffic Light Circuit using the programmable GPIO Pins via Python. In the next tutorial, we will extend the circuit by a few functions (including an Input).
The most common form of 7-segment displays are “Common Cathode”, for which et al. the microchips MAX7219 and MAX7221 are intended. There are also “Common Anode”, which are usually a lot cheaper. However, these are not directly compatible with such a microchip. How it all works is shown in this…
In this tutorial, I want to show you how to set up and use a small infrared light barrier, which gives a signal as soon as the light barrier is interrupted. By traversing both photocells one behind the other, the speed can be measured.
This tutorial demonstrates how to automatically run scripts for text commands via Telegram after the installation on the Raspberry was covered in the previous tutorial. This allows you to, for example, easily query the status of your Pi’s on the go or simply perform actions remotely via your messenger.
Some of you know about the safer WhatsApp Alternative – Telegram. If you also want to send and receive Messages, Pictures and Videos on your Pi, this is the place for you. All you need is an additional Sim Card to receive the SMS. In a later tutorial, we will…
Who has his Raspberry Pi running as a Server, etc., will quickly realize that the little giant can become very hot. To a certain extent, one can surely ignore this, but if the Pi is running day and night, you should pay attention to the temperature (especially in a housing).…
