Hello everybody, I am Walker. Sorry that I am not very well in typing Chinese, so I am going to use English in this passage
Arduino Uno unlike other arduino board, it cannot simply use USB host to do project like: Arduino Mouse, Keyboard...etc.
But I am here to show you how to make arduino Uno to be a USB host with some simple test.
This is my video of Testing USB host keyboard without any USB-shield (Shields are very expensive to a student )
For more details and the steps of the project, please go to my Blog
