Connect and Control WS2812 RGB LED Strips via Raspberry Pi

Felix - 15. November 2017

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 […]

How to setup a Raspberry Pi Security Camera Livestream

Felix - 22. October 2017

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 […]

Build a digital Raspberry Pi Scale (with Weight Sensor HX711)

Felix - 21. May 2017

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 […]

Control a HD44780 LCD display via I2C with the Raspberry Pi

Felix - 15. May 2017

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 […]

Control your Raspberry Pi by using a wireless Xbox 360 controller

Felix - 8. May 2017

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 […]

Build your own automatic Raspberry Pi Greenhouse

Felix - 27. April 2017

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 […]

How to connect and control a Raspberry Pi WS2801 RGB LED Strip

Felix - 7. April 2017

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 […]

Raspberry Pi Heartbeat / Pulse measuring

Felix - 23. March 2017

Not only with fitness watches, but also with the Raspberry Pi it is possible to measure pulse / heart rates. With a small module – the Raspberry Pi pulse sensor – you can easily measure your own pulse and thus monitor permanently your health condition. This sensor can also be used in mobile Raspberry Pi […]

50 of the most important Raspberry Pi Sensors and Components

Felix - 22. January 2016

One of the many advantages of the Raspberry Pi is that it is possible to connect almost all standard Arduino and Raspberry Pi sensors and components to the dhtvarious GPIOs. Moreover you can evaluate and / or process the values with programs and other software. This accessory can be used in projects such as Smart […]

Measuring Rotation and acceleration with the Raspberry Pi

Felix - 30. November 2015

Acceleration and rotation sensors are most known from smartphones. The rotation of the device can be detected and can be addressed directly. With the Raspberry Pi and a Gyroscope / Accelerator sensor it is possible to measure the rotation as well as the acceleration of the 3 axes. In this tutorial I show how to […]

Let Raspberry Pi’s communicate with each other per 433MHz wireless signals

Felix - 26. October 2015

Maybe some of you thought about how to let some RaspberryPi’s communicate with each other wirelessly. For this purpose small 433MHz modules are ideal, which are already available for a few bucks. Therefore in this tutorial I want to show how two (or more) RaspberryPi’s can “talk” with each other. But do not worry, if […]
