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.
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…
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…
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…
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.…
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…
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…
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…
In the first part of the tutorial, I showed how to connect and configure a touchscreen on the Raspberry Pi. In this part, I would like to show some settings that will improve the usage of the display.
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…
In addition to some wireless connections such as 433Mhz, infrared and NFC, Bluetooth is probably the most common and popular mode of data transmission between smartphones, which is why the Raspberry Pi Bluetooth data transfer is interesting. Meanwhile, pretty much all devices support Bluetooth and can not only be paired…
