Arduino + usb keyboard?

Hi!

I'm creating a project and I need some keyboard input to arduno. Is it possible in any way? The texts "path" keyboard-->Arduino-->lcd 16*2 screen.

I'm using Arduino uno at the moment .

The simplest way will likely be to use an USB host shield. If you google that, you would find several well documented versions.

Do you need "some keyboard" or an USB keyboard ?

Problem with arduino is that it has no usb-host capabilities. If it has to be USB, you can use a costly USB-hostshield.

A ps2-keyboard may... be more interesting though, you can read it using 2 pins of your arduino and don't need extra hardware.

After you're receiving characters either way, it should be possible to send them to an lcd.

Hi attepohjanmaa, I think you have to use an usb host shield and the associated Usb_Host_Shield_2.0 library that you can find hosted on GitHub at this link : https://github.com/felis/USB_Host_Shield_2.0. I suggest you to read this page : http://www.circuitsathome.com/mcu/hid-support-for-usb-host-shield-library-2-0-released and here https://github.com/felis/USB_Host_Shield_2.0/tree/master/examples/HID there are some example with keyboard and mouse that are also included in the Usb_Host_Shield_2.0 library.
