MQTT is a protocol that specifically sends data from devices of the Internet of Things and is supported by most microcontrollers and systems. To use Raspberry Pi MQTT communication, not much is needed, which is why this type of transmission is very interesting. In addition, it is really easy to use. In this tutorial, we […]
In addition to creating graphical interfaces via web servers such as Node.JS or Python and TKinter, we also have the option to run GUIs that were created by Visul Studio on the Raspberry Pi. These are created via Windows and then made executable on the Raspberry Pi. Not much is needed! In this tutorial we […]
If you are looking for RGB LED strips, you will probably come across the WS2812 or the WS2801. These two LED strips are very different, but both can be controlled with the Raspberry Pi. After using the latter in a previous tutorial and using it in our Ambilight, this tutorial is about using the Raspberry […]
One of the many applications of a Raspberry Pi is measuring the temperature. In projects like weather stations you want to know the exact value. Using a 1-Wire Raspberry Pi temperature sensor makes it very easy to read it out and you will only need one GPIO pin. In this tutorial it is described how […]
After we are able to record individual images with (USB) cameras / webcams, we also want to view live pictures. This can either take place on the smartphone or on a PC fom outside of the home network. For this purpose, we configure the Livestream of the Raspberry Pi security camera. The great thing is […]
Node.JS is a server platform that uses JavaScript. Originally developed for the Google Chrome browser, it is very resource-efficient, which makes the use of a Raspberry Pi Node.JS web server interesting. In addition to the advantages of asynchronous applications, Node.JS offers a very simple but powerful method to install and use different plugins or libraries, […]
As hardly any scales work analogously, it is of course also possible to measure weights with a digital Raspberry Pi scale. This can be used in various applications as the weight value ranges which can be measured are also almost unlimited. Only a sensor and a load cell are required, which are available for different […]
LCD character displays are a simple and a cost-effective way to display a text. Thanks to the HD44780 controller, the control of the modules has become very simple. However, one must occupy many GPIOs for it. An alternative is the I2C data bus, which means that only two GPIOs are used. In this tutorial a […]
In addition to the control of the Raspberry Pi via infrared remote controls, 433 Mhz transmitter, messengers and many more, also a wireless Xbox 360 controller can be read from the Raspberry Pi. This allows the gamepad to be used as an external mouse (in desktop mode) or in scripts and thus the GPIOs can […]
In an increasing number of cities, the trend is towards organic or even self-grown fruits and vegetables. Perhaps a deterrent cause is the time spent on plant care. Therefore, this project involves the creation of an automated Raspberry Pi greenhouse, which reduces the work to a minimum. By automatic watering, airing and exposure, only harvesting must […]
One of the many Raspberry Pi projects is the lighting of rooms or objects. LED strips are particularly suitable for this purpose, because many individual LEDs are aligned and each individual LED can display all RGB colors. Thus, some projects such as room lighting, Ambilight or e.g. a Christmas tree lighting can be realized. The […]
