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 […]

Raspberry Pi and Arduino – Introduction

Felix - 7. July 2019

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 […]

Log Raspberry Pi sensor data with ThingSpeak and analyze it

Felix - 22. June 2019

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 […]

How to let an Arduino and Raspberry Pi communicate with each other

Felix - 8. June 2019

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 […]

Raspberry Pi GSM Module – Mobile Internet (LTE, 3G, UMTS)

Felix - 25. May 2019

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 […]

Build a Raspberry Pi door / window sensor with Reed Relais

Felix - 19. May 2019

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 […]

Raspberry Pi LCD Display: 16×2 Characters Display (HD44780)

Felix - 21. April 2019

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.

Connect a Raspberry Pi Keypad – Code Lock

Felix - 17. February 2019

For the Arduino and Raspberry Pi there are some keypad matrixes that can be connected and read relatively easily. Similar to the numpad on a keyboard, these keypads have 3×4 or 4×4 keys. These modules can be used, for example, as code locks or for the construction of a small pocket calculator. With help of […]
