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 […]
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 […]
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 […]
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 […]
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 […]
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 touchscreen, however, any other supported […]
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 with it but of course, […]
Thanks to the inexpensive Raspberry Pi Zero, Internet of Things (IoT) projects will continue to grow. One disadvantage which the Zero (not W) and A+ models have is the lack of Ethernet connectivity. That would not be a problem, if not just a single (micro) USB port onboard. In order to connect these models with the […]
Anyone who has ever thought of a car PC has certainly dealt with radio reception. Now there are not too many possibilities to use the Pi as an FM receiver, but one is the Si4703 module, which is used here. In a previous tutorial, I have already shown how to use the Raspberry Pi as […]
As already announced at some point, there will be additional tutorials on how to use an Arduino on the side of the Raspberry Pi. The Arduino is a small microcontroller, which is very cheap to have but allows many additional features to the Pi. In combination, the two offer even more options than the Raspberry […]
