Grundlagen

Relais

Ein Relais ist ein Elektromagnet mit einem angebauten Schalter. Legt man eine Spannung an den Elektromagneten an, schaltet sich der Schalter um. Da der integrierte Schalter nicht elektrisch mit dem Elektromagneten verbunden ist, kann man mit dem Relais externe Stromkreise steuern. Beispiele sind z.B. Handytasten und Tasten von Digitalkameras.
Weil Arduino nicht genug Strom zur Verfügung [...]
