Analoger Input - einfache Sensoren

Die Möglichkeit mit Mikrokontrollern analoge Signale auszulesen, eröffnet uns sehr spannende Anwendungen, doch bevor wir uns in das nächste Beispiel vertiefen, noch ein paar Worte zur Natur der analogen Signale.
Wir hatten gelernt, dass digitale Signale entweder an oder aus sind, d.h. in einem Stromkreis mit 5V Versorgungsspannung ist ein digitales Signal entweder 0V oder 5V.
Ein [...]

Axel-Benz-Formel

Hallo liebe Leute,
auch wenn wir versuchen, die Grundlagen des Physical-Computings so einfach und unproblematisch wie möglich zu gestalten, braucht man leider doch hin und wieder auch eine Formel, wie z. B. diese Axel-Benz-Formel:

Diese Formel hilft einem, den passenden Referenzwiderstand zu einem analogen Sensor zu finden. Ich werde Euch am Beispiel eines Lichtsensors kurz erklären, wie [...]
