Morse code encoder using 8051

[Amir]

I had an idea of creating a morse code encoder using 8051 which will take input from the keyboard for all the 26 alphabets, spacebar and enter key and give its corresponding output in the form of LED flash. Can someone elucidate on how I can go forward with this especially the interfacing of the keyboard?

You can create the keyboard in which keys are arranged in rows and columns (matrix keyboard), then using the scanning method for reading the key.

Do you think there may be an alternative to using a keyboard with a USB port. 
I’ll have to constrct a matrix of 7X4 otherwise like you suggested

Ofcourse possible. But your 8051 don’t have a usb interface module in it. So you need an external usb controller, which then communicate with your 8051. Do you have any idea how complex the coding and circuitory will be??

Honestly I am pretty new in the field of µP and µC, its a college project that we need to make and I had this idea. If its too complex for me to understand then I’d like to learn about it, do you know some really good online sites regarding it. 
And could you suggest some easier alternative project?

Alright. If you are a beginner and wish to learn usb interfacing with a microcontroller, then I would suggest you to start with Arduino board.

I hope the following link will help you regarding the same.
