Belki birilerinin işine yarar.Kendim denedim çalışıyor.

ilk olarak arduino 1.05 ide yüklenmeli.1.65 ideyi yada başka bir ide varsa kaldırılmalı.1.65 de hata veriyor denenmiştir.1.05 versiyonu aşağıdaki adresten indirebilirsiniz.

https://www.arduino.cc/en/Main/OldSoftwareReleases#previous (https://www.arduino.cc/en/Main/OldSoftwareReleases#previous)

Aşağıdaki adresten kütüphanemizi indiriyoruz.Kütüphaneyi rardan çıkardıktan sonra libraries klasörü içindeki Usbkeyboard adlı dosyayı arduinonun bulunduğu libraries klasörüne atıyoruz.

https://code.google.com/p/vusb-for-arduino/downloads/list (https://code.google.com/p/vusb-for-arduino/downloads/list)

Örnek: D:\Program Files (x86)\Arduino\libraries

Gerekli malzemeler:

- Arduino Uno veya Atmega328PU
- USB kablo yada soket A ya da B olabilir.
- 68 ohm direnç 2 tane
- 2.2k ohm direnç 1 tane
- 3.6V zener diyot 2 tane
 

Devre Şeması: Şemadaki pinler arduinodaki aynı isimli pinlere karşılık gelmekte.Devreyi kurup pc nin usb girişine bağlandığında pc bunu usb hid aygıtı olarak tanımaktadır.Ayrı bir driver gerekmez.

/**
* VirtualUsbKeyboard
*
* Enumerates itself as a HID (Human Interface Device) to a host
* computer using a USB shield. The Arduino then appears to the host to
* be a USB keyboard and keypress events can be sent on demand.
*
* This example watches the state of 6 push buttons and when a button
* is pressed it sends a matching keypress event to the host.

Teşekkürler. Vakit bulursam yapacağım. USB'si olmayan mikrodenetleyiciden HID Klavye nasıl yapılıyor öğrenmek istiyorum.

@ds01  Yaptım Çalışıyor fakat KeyUp KeyDown yok. Ne yapcaz.
