so for my DLD project i wanted to create a simple keyboard that will display alphabets small and capital with help of shift and numbers 0 to 9 along with space.

i have created a circuit that will give me the desired ascii code of that character but i dont know how to display it i had an idea where i integrate it with ps2 output pin and connect it with a system

Display where? On a computer? What os? What kind of experience do you have? Have you looked at any of the build a keyboard guides?

 

I've never done it and only looked at doing things using arduino to synthesis a keyboard to do more complicated things. Probably overkill for this.

can you tell me a simple way to show the output like using lcd screen with a microcontroler or some other chips?

i have not looked into the transfer of data into the pc yet but have studied the structure of keyboard

With arduinos with on chip USB/serial there are prewritten functions to do it. The problem you'll have is coming up with ways to map all the keys to a limited set of inputs. I've not looked into this too much.

 

There must be a more traditional way to do this, there are hundreds of tutorials on building custom keyboards.
