Raspberry Pi with SATA in a case
Ich habe mir mal wieder was zum Basteln bestellt. Einen Raspberry PI 3B, eine Zusatzplatinen mit einem SATA Anschluss und ein passendes Gehäuse. Diese Kombi soll den PI im Keller ablösen, den ich als Entwicklungsserver verwende. Komponenten Ich verwende folgende Komponenten: Raspberry PI 3 B MakerHawk Raspberry Pi X820 2.5 Inch SATA HDD/SSD USB3.0 Storage …

MQTT Protocol + Experimental Setup
I came across the term MQTT online and really liked the approach behind it. So, I treated myself to a small experimental setup, which I've described below. First, a few details about MQTT. About MQTT General Information MQTT governs communication between data sources and data sinks using a broker. Data Source Sources for…

Raspberry Pi Zero W – Headless Installation
Hier findet ihr eine Anleitung zur Erstinstallation des Raspberry Pi Zero W ohne Monitor und Tastatur mit Hilfe eines Windows PCs. Der Vorteil den Pi Zero W „Kopflos“ (aus dem eng. Headless) zu betreiben ist, dass man die ganzen Adapter für HDMI und USB erstmal nicht braucht. Ausserdem muss man nicht einen extra Monitor besorgen …

Raspberry Pi + Servo
Controlling a servo with the Raspberry Pi 3. This is about the basic technique; the application could be, for example, a mobile robot. The servo is to be controlled via software PWM in order to keep the hardware PWMs free for other functions. Additionally, the servo should not be controlled via integer values as is usual...

Pi4J + BlueJ
Since I prefer to program in Java, I use the Pi4J library to control the GPIOs on the Raspberry Pi 2 and 3. I will not go into detail about the installation of the library, as this has already been exhaustively described on the following web pages. http://pi4j.com/install.html http://pi4j.com/utility/pi4j.html http://www.forum-raspberrypi.de/Thread-tutorial-ansteuerung-der-gpio-ports-mit-pi4j It is also important to know that Pi4J builds on the wiringPI library…

Raspberry Pi 3 + Motor Control
The aim is to operate two DC motors using a Raspberry Pi 3 with the help of a motor driver board. This will later be used to power a two-wheeled robot. Hardware: Pi 3 (or older, please pay attention to the correct pins) Motor driver board L9110s 2x DC motor Various cables (pre-made pin-header cables) Test setup GPIOs on the Raspberry Pi Motor1 direction GPIO 26…

Controlling the US-100 distance sensor with a Raspberry Pi 3
Controlling an US-100 ultrasonic distance sensor with a Raspberry Pi 3 (or earlier). I have only found tutorials for the SR-04, but this is integrated analogously to the US-100. Hardware Pi 3 (or older, please pay attention to the correct pins) US-100 (ultrasonic sensor) Breadboard (for easier setup) Various cables (pre-made pin header cables) Setup The US-100 operates at 3.3V…

Controlling the Raspberry Pi 3 LED
Hier der erste Versuch eine LED mit dem Raspberry PI 3 anzusteuern. Aufgebaut wird das Ganze auf einem Brotboard mit Freiluft-Verkabelung. Hardware PI3 (oder älter bitte auf die richtigen Pins achten) LED (Ich habe ne grüne Standard-Led 1,5V) 220 Ohm (Vorwiderstand für die LED) Brot-Board (zum leichteren Aufbau) Diverse Kabel ( Vorgefertigte Pin-Header Kabel) Aufbau …
