Dear friends,
I was googling about how to use esp32 like a usb keyboard, but it doesn't seem feasible and youncan't use the arduino keyboard library.
It seems only certain arduinos can use keyboard library: Leonardo, micro, arduino 2, mkr serie.
I opted for sparkfun micro pro, because I found it in the electronic shop behind the corner.
At first glance I was very surprised for the size, it's incredible small, apart that, keyboard libraries works perfectly on it.
You will wonder why am I interested in such a device?
The reason is because I red of a device called bash bunny.
That'an interesting concept, because the idea of simply connect to the computer an usb keyboard and automagically control it is the fantasy of my childhood and it is used in many Hollywood movies.
In past I thought to simulate a cdrom with an arduino, because it you pur certain files on a cdrom the old versions of windows executed it when you3 inserted the cdrom without asking, but the latest versions of windows asks.
Basically as usb key emulator you can do anything on the computer. You can login, activate the command prompt or the powershell prompt and write your program and execute it. Top can have the total control of the system.
For example it you want to start the command prompt, voi nave to use this code:

Keyboard.begin();
Keyboard.press(KEY_LEFT_GUI);
Keyboard.press('r');
Keyboard.releaseAll();
delay(2000);
Keyboard.press(KEY_RETURN);
Keyboard.releaseAll();
delay(2000);
Now you can write your commands

It you want to type many characters, you need an sd reader to connect to the micro pro. Usually sd card readers requires 5volt. You can use the usb to obtain this Voltage. I bought the 3.3 volts version of the micro pro because I wanted to connect it to the esp32, but there is also a 5v version.
