4.18 Keyboard library for Arduino

Arduino's keyboard library lets the Arduino board with USB capabilities to act as a Keyboard. Functions of the keyboard allow 32u4 or SAMD micro boards to transmit the keystrokes to the connected keyboard using a micro native USB port. Although sometimes it becomes difficult to program the keyboard if the keyboard library is continuously working. In such a situation, functions like Keyboardprint () and Mouse.move () are proven to be very helpful as they send the keystrokes only when a user is ready to handle them. Using a controlled system like a switch is recommended to be used in order to switch this functionality on. Using Serial.print() function is also very handy when the keyboard or a mouse library is used ad it ensures the values which are to be printed.

Available Functions in Keyboard library are:

Keyboard.begin (): It starts emulating a keyboard that is attached.

Keyboard.end (): It stops the keyboard emulation.

Keyboard.release (): This function releases the particular key.

Keyboard.printIn (): Keystrokes to the attached computer are sent with this function.
