Transistoren

Transistoren werden zur Verstärkung und zum Schalten von Signalen (Strömen) benutzt. Will man Schaltkreise mit größerem Strombedarf kontrollieren, muss man den Strom, den das Arduino-Board liefert verstärken.

Einen typischen npn-Transistor hat drei Beinchen. Hält man ihn mit den Beinchen nach unten und der flachen Seite nach vorn, werden die Beinchen von links nach rechts Emitter, [...]
