11.0 Einleitung
In diesem Kapitel beschäftigst du dich mit der Steuerung von Elektronik über den GPIO-Anschluss (General Purpose Input/Output) des Raspberry Pi.
Die meisten Rezepte erfordern ein lötfreies Breadboard und Überbrückungsdrähte von Stecker zu Buchse und von Stecker zu Stecker (siehe Rezept 10.9). Um die Kompatibilität mit älteren 26-poligen Raspberry Pi-Modellen zu gewährleisten, werden in allen Breadboard-Beispielen nur die oberen 26 Pins verwendet, die beiden GPIO-Layouts gemeinsam sind (siehe Rezept 10.1).
Einen Bausatz mit Teilen und einem Breadboard, die für viele der Rezepte in diesem Kapitel geeignet sind, findest du in der Project Box 1 für Raspberry Pi.
11.1 Anschließen einer LED
Problem
Du willst wissen, wie man eine LED an den Raspberry Pi anschließt.
Lösung
Schließe eine LED an einen der GPIO-Pins an und verwende einen 470Ω oder 1kΩ Vorwiderstand, um den Strom zu begrenzen. Für dieses Rezept brauchst du Folgendes:
-
Steckbrett und Überbrückungsdrähte (siehe "Prototyping-Ausrüstung und Kits")
-
470Ω-Widerstand (siehe "Widerstände und Kondensatoren")
-
LED (siehe "OptoElektronik")
Abbildung 11-1 zeigt, wie du diese LED mit einem lötfreien Breadboard und Überbrückungskabeln von Stecker zu Buchse verdrahten kannst. Die LED hat einen positiven und einen negativen Anschluss. Die positive Leitung ...
