Human Interface Device (HID)

Human Interface Device (HID) ist eine Geräteklasse des USB-Standards für Computer, welche Geräte beschreibt, mit denen Benutzer direkt interagieren. Meist wird HID bei Geräten wie Tastatur, Maus, Joystick und Grafiktabletts verwendet. (Wikipedia)

Es gibt eine HID bibliothek die im Arduino eingebaut ist (“Built-in”). aber sie funktioniert nicht mit einem Arduino Uno, aber doch mit der Flora.

In Arduino, unter: Datei —> Beispiele —> 9.USB……. 

findet ihr unter anderem folgende beispiele:

Hier ein simples beispiel für die Flora, das folgende sensor/knopf werte in maus und keyboard eingaben umwandelt:

A9 => mouse x koordinate

A10 => mouse y koordinate

6 => “hallo“

12 => “du”

/*
VERY SIMPILE CODE
for controling mouse x,y
and tying some text

CODE inteded for a Flora V3

CIRCUIT:
analog sensor between pin9 and GND
analog sensor between pin10 and GND
digital button between pin6 and GND
digital button between pin12 and GND

ACHTUNG. wenn du dieses beispiel läufts wird es deinen computer übernehmen. du kannst aber jederzeit die Flora abstecken, um wieder kontrolle zu bekommen:-)

Ich wünsche viel Spass!!!
