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 dhtvarious 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 […]

Raspberry Pi GPIO Explanation for Beginners + Programming (Part 2)

Felix - 28. May 2020

One of the special features of the Raspberry Pi is the programmable input-output pins. These so-called GPIOs can easily be switched via a program, which we will go through in this tutorial. For this we will write a Python program, on the one hand, we record inputs and on the other hand, we switch the […]

Learn How to Program on the Raspberry Pi – Part 1: Introduction

Felix - 9. May 2020

Many (absolute) beginners get a Raspberry Pi as a gift, but have often little or no programming knowledge. Therefore I would like to clear that hurdle in this series of tutorials and encourage learning to program with the Raspberry Pi. The big advantage is that we can also write a hardware-related code, which allows us […]

Creating a Raspberry Pi SSL Certificate For Free With Let’s Encrypt

Felix - 1. May 2020

A connection via SSL/TLS protects the data traffic by sending packets encrypted. To be able to establish such a connection, you need a certificate from a trustworthy provider, which usually costs over $20 per year. Thanks to the Let’s Encrypt Initiative, such SSL certificates are now available to everyone – free of charge. The big advantage […]

Tips & Tricks (FAQ) to the official 7″ Raspberry Pi Touchscreen

Felix - 1. May 2020

The official Raspberry Pi touchscreen module offers many options and makes many other touch displays look old for a similar price. Not only is the very accurate 10-finger capacitive touch a positive, but also no GPIOs or HDMI ports are occupied. In order to cover many topics, I have created this article, where some frequently asked […]

Develop Your Own Raspberry Pi Alexa Skill and Control Pi Remotely

Felix - 15. April 2020

Voice control is an increasingly important component in smart homes. For this purpose, Amazon provides skills that run on Amazon Echo Dot, Fire TV sticks, smartphones and other devices. In this way, Raspberry Pi Alexa skills can also be created in a simple manner. The skills can be published optionally and even money can be made with […]

MCP3008: Read out Analog Signals on the Raspberry Pi

Felix - 6. April 2020

Many of the sensors originally developed for the Arduino do not offer a digital interface and can only be read out analog. The problem is that the Raspberry Pi with its GPIOs cannot read out any analog signals, which is why you need an analog-digital converter (ADC) like the MCP3008. This means that up to […]

Reading Out Raspberry Pi RFID RC522 Tags (NFC)

Felix - 26. March 2020

RFID is a technology whereby data is transmitted without touch, which is used in chip cards. Access cards can be read out with a Raspberry Pi RFID module (RC522) and thus e.g. access to doors or locks can be given. Current smartphones have similar ones. In this tutorial, I will show how to read RFID […]

Controlling the Raspberry Pi RTC Module – I2C Real Time Clock

Felix - 9. February 2020

The Raspberry Pi does not save the date permanently. With the help of the Raspberry Pi RTC (Real Time Clock) module DS1307 you have a real-time clock – regardless of an existing internet connection. This is an advantage in many applications that require a timestamp but cannot be connected to the Internet. Especially for outdoor […]

Raspberry Pi as a Jukebox (Spotify, Soundcloud, TuneIn, and much more) – Online Radio

Felix - 27. December 2019

Small internet radio stations seem to be very popular at the moment. They are being installed more often in the bathroom, kitchen or living room because on the one hand they have more programs than the old-fashioned radios and on the other hand the sound quality is getting better and better. But what these Internet […]

LCD Touch Display (3.2″) on the Raspberry Pi

Felix - 19. December 2019

Sooner or later, most hobbyists will buy a touchscreen. The smaller touchscreens are already available from 10-20€, but the advantages are big (especially with regards to a GUI for home automation, for example) and the effort is relatively low, as I’ll show. As an example I will use a 3.2” SainSmart touchscreen, however, any other supported […]
