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 […]

Control Raspberry Pi Wireless Sockets (433MHz) – Tutorial

Felix - 16. April 2018

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 […]

Raspberry Pi servo motor control

Felix - 16. April 2018

In addition to stepper motors, there are also small and cheap servo motors. The control of Raspberry Pi servo motors is very simple and thanks to the small size and weight they are used in many areas. Unlike stepper motors, servomotors can be controlled with a single GPIO. In this tutorial, I’ll show an example of […]

Build Raspberry Pi GPS location/navigation device

Felix - 13. April 2018

While every smartphone has GPS, the Pi can also be converted into a GPS receiver with a cheap Raspberry Pi GPS module. In many outdoor applications, especially those that move (Car-PC, weather balloon, etc.), the exact position is a big advantage. Mobility is achieved with a battery pack or a USB power bank. In this […]

Connect and control Raspberry Pi motion detector PIR

Felix - 9. April 2018

Due to its design, the PIR motion sensor module is very easy to use because it already has the components installed. Raspberry Pi motion detectors in home automation and/or outdoor applications (as a classic outdoor motion detector) are easier than ever to implement. I will show the commissioning in this tutorial.

Remote Control a Raspberry Pi with 433Mhz Radio Transmitter

Felix - 6. April 2018

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 […]

How to build Raspberry Pi voice control (home automation)

Felix - 6. April 2018

Siri, Amazon Echo and “S Voice” are all voice recognition programs designed to make life easier. Even a Raspberry Pi voice control can be easily built by yourself. Because such a speech recognition is of course very beneficial for home automation. In this tutorial, I’ll show you how to digitize speech through a microphone, convert […]

Run a Raspberry Pi on rechargeable Batteries

Felix - 30. March 2018

Mainly in mobile applications, a static power supply is not always guaranteed or there is no outlet nearby. A Raspberry Pi battery pack or a mobile power supply is beneficial in many cases. In this tutorial, I want to show one way to operate the Pi using normal AA batteries or rechargeable batteries. Of course, […]

Use a Joystick on the Raspberry Pi (with MCP3008)

Felix - 26. March 2018

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.

Raspberry Pi Security Camera with Webcam

Felix - 26. March 2018

A Raspberry Pi surveillance camera can be a cheap alternative to common variants like IP cameras. An ideal Raspberry Pi camera module represents normal webcams that can be used as well, connected via USB. This tutorial shows how to use a webcam with the help of the software fswebcam. In addition, I show different settings […]
