## 附录（ keyboard库介绍） ##

见文知义keyboard库，功能就是将arduino 模拟成一个usb键盘。 Api如下  
Keyboard.begin()  
Keyboard.end()  
Keyboard.press()  
Keyboard.print()  
Keyboard.println()  
Keyboard.release()  
Keyboard.releaseAll()  
Keyboard.write()

Keyboard. press (键值); 输入：键值  
如Keyboard. press(‘A’);  
如Keyboard. press(KEY\_LEFT\_GUI);//左win 实际输出：  
模拟usb键盘上键值所对应按键被按下

输入键值与按键的对应关系见键值表

Keyboard.release(键值) 输入：键值  
如Keyboard.release(‘A’);  
如Keyboard.release(KEY\_LEFT\_GUI);//左win 实际输出： 模拟usb键盘上键值所对应按键被松开

输入键值与按键的对应关系见键值表

PS：Keyboard. press()和Keyboard.release()请成对使用，防止出现按键被按下没有松开的情况

Keyboard.print(character);//模拟键盘敲出一个字符 Keyboard.print(characters);//模拟键盘敲出一串字符的过程 输入：字符或字符串  
如Keyboard.print(“A”);  
Keyboard.print(“ABCDE”); 实际输出  
模拟在usb键盘上敲出单个字符或字符串的过程

Keyboard.println(character)// 模拟键盘敲出一个字符并添加换行的过程 Keyboard.println(characters)// 模拟键盘敲出一串字符并添加换行的过程 输入：字符或字符串  
如Keyboard.print(“A”);  
Keyboard.print(“ABCDE”); 实际输出  
模拟在usb键盘上敲出单个字符或字符串并添加换行的过程

Keyboard.releaseAll() 输入：无

实际输出：释放所有按键；

键值表：
