Keyboard-Hack / Was geht als Schalter?

Damit der Keyboard-Hack möglichst witzig wird,
kann man den normalen Drucktaster (wie er ja im Keyboard ist) durch ‘ne ganze Reihe von anderen obskuren “Sensoren” ersetzen.

Neigungsschalter

Neigungsschalter

Geeignet sind dafür prinzipiell alle digitalen Schalter/Sensoren.

Wichtig ist, dass sie einen Kontakt öffnen und schließen können (digitale Sensoren).

Darunter fallen:
- Taster in allen Varianten (Drucktaster, Wippschalter, etc…) [Conrad 700460 - 62]
- Neigungsschalter [Conrad 700444 - 62]
- Magnetschalter (z.B. Tür-Kontakt, Reed-Schalter) [Conrad 503703 - 62]
- einfache Bewegungsmelder
- selbstgebastelte Schalter

Selbstgebastelt? Alle leitfähigen Materialien die man irgendwie
zusammenbringen kann, sind schon ein Schalter!

In manchen Fällen funktionieren auch einfache analoge Sensoren.
Ein einfacher Lichtsensor [Conrad 145475 - 62] oder Drucksensor [Conrad 182389 - 62] kann auch an das Keyboard gelötet werden. Man hat allerdings dann keinen Einfluss darauf, ab welcher Helligkeit bzw. welcher Kraft der Kontakt geschlossen ist. Da heißt es ausprobieren.

Die Conrad-Nummern lotsen euch auf www.conrad.de zum richtigen Artikel um sich mal einen Überblick zu verschaffen. Wie bereits gesagt, gibts die meisten Sachen bei Segor oder Reichelt günstiger.
