Controling of Keyboard Navigation Keys using External Aurdino Push Button

Projects General Guidance

Hi,I am a Beginer to Aurdino,I need to program to Control the Keyboard Navigation Keys using External Aurdino Push Buttons.

2

What do you mean by "Keyboard Navigation Keys"?

...R

i mean left ,right, up and down navigation buttons

4

The keys can be pressed by a short circuit of their contacts, or mechanically by e.g. servo motors.

Yes. But you still have not told us where these mystical buttons are located. Are they on some machine?

i will clear my concept
while giving ppt you have to press left or right buttons for next or previous slides
instead ofthese left or right buttons on keyboard i need to use two arduino push buttons to do the same work
i am not from a coding background and now in a IT company for training and my instructor told to get code for above operation and analyse the code
please help me with this
because i am not getting any readymade code for above case (since it deals with interface with internal device like PC...: one of my freind from EC told)
also which type arduino should i use (uno,mega...)
thank you

I think what you are really trying to say is that you would like an Arduino to be able to generate key-presses on a PC that it is connected to.

If you had said so in your Original Post you would have received the info in the first Reply that an Arduino Leonardo or Micro can mimic a PC keyboard - it's all in the Reference section
