Hello i got the basics down for the arduino keyboard. from this page.Click here. But i was wondering if there was any other commands like volume up and down or the print screen as well as other functions that a normal keyboard can do? Thank you.
Have a look here.
Thank you riva I'm looking at it now.
Hello i have a question sense I'm making my own keyboard i was wondering what kind of a delay should i give from the time the button is pushed to the time i release the key?

I would think something between 5ms and 30ms would be fine, try it and see. If your using real buttons then you may need to allow longer for button debounce so you don't get false triggers.
Hello Riva thank you. Currently I'm just using some of Ebay switches Which was very very cheap for testing something like this. Later if i get things working i would like to make bigger side keyboard well same buttons count but bigger size buttons or my fingers lol. What buttons would you recommend to use? I was looking at some of these cherry mx switches But cost of them are a little high for each one. about $2.50 dollars each was the cheapest i found on From ebay also
Another thing i notice if doing a matrix setup for keyboard diodes are what is needed on each one now is that going on the column side or the rows side?
The last thing is i was seeing was something for a Vusb type of keyboard they call it a arduino hid type of keyboard. i looked more into it and some awesome stuff on it but not really sure what it really is some type of interface sense it's not using the ftdi of the arduino to interface with the pc?
right now I'm using the standard keyboard from arduino website Click here And seems to be working for the most part i can not do a volume up or volume down as well i can not find a fn key on the site.
Grrr links not working correctly these are the links

From the link in your initial post I assumed you was using the Leonardo to act as a keyboard/mouse to the PC but now I'm not sure what type of Arduino your using. The microcontroller on the Leonardo has a USB interface built int so does not need an external chip like the FTDI to convert UART serial to USB serial. Because of this you can also configure the built in USB to look like a HID (Human Interface Device) keyboard/mouse/joystick to the PC it's plugged into.
V-USB is software that can run on standard Arduino's like the UNO and with a few external components can emulate the USB interface. The software can be configured to make this interface look like several different types of thing like Serial/Keyboard/mouse/joystick but is quite complex to configure compared to the built in libraries for the Leonardo.right now I'm using the standard keyboard from arduino website Click here And seems to be working for the most part i can not do a volume up or volume down as well i can not find a fn key on the site.
What model of Arduino are you using and if it's not the Leonardo then how is it wired up so it looks like a keyboard to the PC it is plugged into?
Hello I'm sorry i didn't say which one did i my mistake. I have a Leonardo one. Well it's a arduino pro micro also from ebay http://www.ebay.com/itm/231451407743?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT it has the leonarduino bootloader on it.
Hello i know it's been a long while sense i posted on this topic. But i have a question some DIY keyboards i found online has Diodes going down each Column and I'm not sure what they would be using it for. Can someone please help me out and understanding why would you need Diodes for?
