Arduino Game Controller

• i tried to draw the circuit on tinkerCAD , it was not perfect solution , i did not fid Arduino Leonardo or even the tilt sensors but i am planning to download a free opensource fritzing version, ASAP

• soldering part i soldered all buttons ground to each other and did the same with the tilt switches grounds and +ve terminals too then i got a signal for every button and switch to connect to the Arduino's pins

to use the usb input device on a pc

we have to include a library called Keyboard.h

this library make sure connection is established through the USB and PC as input devices

so ... after that we start adding variables for every button and for Tilt switches too and assign a pin for everyone of them

then i added another to empty variables that i will fill them with tilt switches reads,

i add a variable for delay time to not manually change every delay string in testing phase.

next three variables are for switching moods (buttonPushCounter, buttonState and lastButtonState )

in this part of coding its a loop that run only ones at the begining of the code :

• i make sure the code know what to do with every variable or Assigned Pins : (inputs < for buttons in my case) and we add _PULLUP to it to activate the pullup resistor of that pin

• switches also are inputs but we don't need _pullups it has a resistor on its board already

• i also started the serial Port with a serial.begin(9600);

this for testing purpose

• i also start Keyboard.begin();

this starts the USB Control over the PC

in this part of coding its a loop that run continuously and loops back over and over non stop

• this part of the code i will put the mode selector part that will switch modes after pressing a button a count of times.

• and it will call either of the next two functions or Modes

here is the link for it: https://docs.arduino.cc/built-in-examples/digital/StateChangeDetection

this function or Mode will assign a keyboard arrow key to every button

• you can add a hex number of one of the keys on a pc keyboard or you can write down its reference modifiers. with a Keboard.press();

i found some of the (hex no and modifiers ) here is a link : https://www.arduino.cc/reference/en/language/functions/usb/keyboard/keyboardmodifiers/

• i add a Serial.println(); for testing purpose

• and in the end of the function i add a Keboard.releaseAll(); this make sure you have some control over your own pc :D or you can end up with a ddddddddddddddddddddddddddddddd continuous for ever :D :D

• and also don't forget to add a delay after keypress and test how many characters you get when you press a button once i made the delay about 100 but testing is the answer :\

this function or Mode will assign the tilt switches to press a key to click arrow left or right instead of the buttons.

• i assigned the read variables of every tilt switch to each of its own variable.

this was made so i can do a differentiation larger than or equal to them 1 or 0

if the readings of the sensorRight > sensorLeft

1 > 0

it will Keboard.press(); to the right and if not (else) it will move to the other direction , i also add key release and delay time and serial prints as previous for testing.

i learned a lot in this Project

• sheet metal < fusion360

• living hinge < pattern spacings with experimentation

• learned about kerf of the laser machine

• Arduino keyboard .press .release and .begin < coding
