Ansteuerung eines Magnet statt über PWM über Analogspannung

[GeorgB]

Das wäre eine Superlösung - danke für den Hinweis!
Wie geht das beim Arduino? Gerade gegoogelt: geht das so einfach?
Nach dem Artikel schreibt man diese eine Zeile einfach ins setup. (http://arduino-info.wikispaces.com/Arduino-PWM-Frequency)
Hat das einen Nachteil?
