Raspberry Pi Heartbeat / Pulse measuring

Felix - Mar 23, 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 […]

Configure and read out the Raspberry Pi gas sensor (MQ-X)

Felix - Mar 17, 2017

Sensors are necessary to detect the components of the air. These are used e.g. in smoke detectors. However, instructions for using these gas sensors at the Raspberry Pi are rare, which is why in this tutorial the general use of such MQ modules at the Raspberry Pi is shown. Thus, e.g. smoke detectors or air […]

50 of the most important Raspberry Pi Sensors and Components

Felix - Nov 27, 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 various 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 […]

How to setup a Raspberry Pi FTP Server – Webserver Installation

Felix - Feb 09, 2016

For uploading files on a Raspberry Pi you should install a FTP server. Such a server is very useful if you use your Pi as a web server or even if you want to have a network storage, which can also be accessed outside of your network if an DNS server is installed. However this […]

Raspberry Pi Stepper Motor Control with L293D / ULN2003A

Felix - Nov 14, 2015

Stepper motors are ideal for applications where it is necessary to know the angle of rotation, for example in robotics. Unlike a normal motor, stepper motors can control the steps individually and can therefore detect the exact position. For easy controlling such a motor, a driver IC like the L293D or the ULN2003 are needed. […]

Using a Raspberry Pi distance sensor (ultrasonic sensor HC-SR04)

Felix - Nov 11, 2015

For many (outdoor) projects a distance measurement is necessary or advantageous. These small modules are available starting atĀ 1-2 bucks and canĀ measure the distance up to 4-5 meters by ultrasound and are suprisingly accurate. This tutorial shows the connection and control.

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

Felix - Oct 26, 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 […]
