Often you want to be able to control (household) devices with a higher voltage with the Pi. Raspberry Pi wireless-controlled sockets are ideal for this because they are very easy to control and you do not have to interfere with the circuit. For that and many other projects, there are wireless sockets, as they can […]
Whoever is aiming for home automation will sooner or later certainly think about the wireless operation. The 433Mhz frequency is ideal for this because there are many cheap transmitters and receivers as well as a wide range of available libraries and scripts. In this tutorial, I want to show how to use a small handheld […]
For some applications, such as games, a joystick can be useful or be even necessary. Since these usually work purely analogously, the signal has to be converted, which we do with the MCP3008 chip. Connecting and reading a joystick is shown in this tutorial.
This tutorial demonstrates how to automatically run scripts for text commands via Telegram after the installation on the Raspberry was covered in the previous tutorial. This allows you to, for example, easily query the status of your Pi’s on the go or simply perform actions remotely via your messenger.
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 […]
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 […]
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 […]
