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 […]
Frequently, a lot of data is generated in projects that run around the clock. One way to store them permanently is to store the data in a local database. However, there are also some reasons that speak against it. In order to keep the measured data (for example, from a weather station) available in the […]
I have already described in a previous article how the Arduino works and which models exist. There are plenty of articles on the Arduino itself, but few in connection with the Raspberry Pi, but this combination offers many possibilities. Since I want to show more about the Arduino in conjunction with the Raspberry Pi, I […]
The Raspberry Pi can be connected to the Internet very quickly and easily via the local network. But what if you also need a mobile Internet connection outside your own WLAN? There are GSM modules / Surfsticks (mostly from Huawei), which can be connected via USB. Sometimes are such GSM modules, which support 3G, UMTS […]
In addition to a surveillance camera and motion sensors, information about open windows and doors is also of interest to a self-built surveillance system. A check with infrared light barriers or other methods would certainly be possible, but in this case, that is much more complicated. In this tutorial, it will be shown how to easily […]
The most common controller of multi-line character displays is the HD44780. There are several Raspberry Pi LCD display sizes (8×2, 16×2, 20×4, etc.) that run with it. In this tutorial, I will show how to use a 16×2 character display and also run a test script.
Almost every project is possible with the Raspberry Pi. This includes also a complete Raspberry Pi Tablet that we can use for different applications. Either as a multimedia tablet or as a panel for the smart home. In this article, I’d like to introduce the Sunfounder RasPad – a beginner-friendly 10.1-inch Raspberry Pi tablet that […]
