I want to learn to wirelessly transmit keyboard commands to a computer, where do I start?

Assuming I want to make a USB keyboard wireless, where do I begin?

Any kits here that will help?

Just bumping this because there was no response.

Hi @human, as the littleBits Arduino is a leonardo clone, here is a good place to start:

At first, you have to understand how USB keyboard works ( wired )

  1. If you understand that, after you have to understand how to pass wireless signals to USB technology
