Modify a USB keyboard into a USB/Bluetooth keyboard with DUE + Bluetooth module

Hello I am new to Arduino, and started about a week ago.

The reason I stepping into this area was because I wanted to mod my mechanical keyboard into a USB/Bluetooth keyboard.

After getting all the information I could have searched, I found that using Arduino Due with a bluetooth module should be an option.

But obviously I hit some roadblock, I came up here for some advice about my plan.

Can someone give me a direction about coding, or there is a better way to do it?

P.S I am from Taiwan and still developing my English. Sorry I wasn't able to describe much more, but

I will try hard to understand what you guys are saying. :)

Thank you so much, Barry

What's your roadblock?

You must make the Due an USB master, with the USB keyboard as slave.
