Arduino Codeįor the Arduino Leonardo, Micro or Due ReadsĪ byte from the serial port, sends a keystroke back. Copy and paste the keypad library file inside the file with the name ‘libraries’ highlighted with yellow color. Notes − You must include the keypad library in your Arduino library file.
Coding in the Arduino language will control your circuit. Open the Arduino IDE software on your computer.
Just connect your board to the computer using USB cable. 1 × Arduino Leonardo, Micro, or Due board.This sketch is designed to only send a Keyboard command after the board has received a byte over the serial port. To ensure you do not lose control of your computer while running a sketch with this function, set up a reliable control system before you call Keyboard.print(). Warning − When you use the Keyboard.print() command, the Leonardo, Micro or Due board takes over your computer's keyboard. The sent keystroke is one higher than what is received, so if you send an 'a' from the serial monitor, you will receive a 'b' from the board connected to the computer. When received, the board sends a keystroke back to the computer. This example listens for a byte coming from the serial port.
