You have to change the Keybindings for your needs!

ArduinoCode:

#include <Keyboard.h>

#include <Keypad.h>

int ledPin = 10;

const byte ROWS = 4;

const byte COLS = 3;

char keys[ROWS][COLS] = {

{'a', 'e', 'i'},

{'b', 'f', 'j'},

{'c', 'g', 'k'},

{'d', 'h', 'l'},

};

byte rowPins[ROWS] = {6, 7, 8, 9};

byte colPins[COLS] = {15, 14, 16};

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );

void setup() {

Keyboard.begin();

}

void loop() {

analogWrite(ledPin, 250);

char key = keypad.getKey();

if (key) {

switch (key) {

case 'a': // Ship POWER

Keyboard.press('u');

case 'b': // Ship Engin
