Use Arduino's USB library to relize the keyboard data input.
1.Function "Keyboard.write();" means that only press key one time. Function "Keyboard.press()" means that always hold the key, to cooperate with function "Keyboard.releaseAll()" used together;
2.Input case alphanumeric directly and use single quotation to mark. For example, input character "M": "Keyboard.write('M');". Input special key, you can find the key nambe in file "hardware\arduino\cores\arduino\USBAPI.h", if you want to input "enter", just like this:"Keyboard.write(KEY_RETURN);".
3.Read the I/O port voltage to judge the if the encoder was pressed which use to simulate the "Ctrl+Tab".
4.Use the interrupt to judge the directory of encoder, then choose the value. We have changed the firmware, so you need download Microduino's firmware package.
5.doEncoder() use to simulate the up and down key.
6.In main function to judge if the encoder was pressed to simulate "Ctrl+Tab".
Rotary encoder simulates the keyboard to realize the up and down key. Press the encoder to simulate the "Ctri+tab". You change the key value to finish other experiment.
