Final Project

Classic Memory Game

Having learned some basic MATLAB coding and GUI design this semester, I decided to challenge myself by making a classic game like Snake or Tetris. Well, turns out they both are still a bit too challenging, so I made the classic card-matching memory game; and with the help of mobile sensors, a player can match pairs remotely with a phone. Try it!!

Code & Files

Mobile Acceleration Sensor Test:

(When the phone is horizontal to the ground and the screen facing...)

UP: Z > 9 (no obvious change in X, Y)
DOWN: Z < -9 (no obvious change in X, Y)
LEFT: X > 8.5, Z < 4 (no obvious change in Y)
RIGHT: X < -8.5, Z < 4 (no obvious change in Y)

(When the phone is vertical to the ground and the screen facing yourself... )

Y > 8, Z < 5 (no obvious change in X)

-There are more but these five are which I used.

Simulink & Stateflow:

My Code:

Get data from mobile sensor. (Acceleration)

m.Logging = 1;              %start getting data from mobile sensor

pause(2);

m.Logging = 0;              %stop getting data from mobile sensor

Fetch only the last data from the array.

[A, T] = accellog(m);       %save data into array A

xAcc = A(:,1);

x=xAcc(end);                %fetch only the last data from the array

yAcc = A(:,2);

y=yAcc(end);

zAcc = A(:,3);

z=zAcc(end);

Load Simulink.

load_system('untitled');    %load Simulink file

sim('untitled');

Test the result.

if  direction == 1

    disp('UP');

    pause(3);

elseif direction == 2

    disp('DOWN');

    pause(3);

elseif direction == 3

    disp('LEFT');

    pause(3);

elseif direction == 4

    disp('RIGHT');

    pause(3);

elseif direction == 5

    disp('GUESS');

    pause(3);

end

Use SWITCH to keep track of the card (change font color to BLUE) and to decide which button to press when the result is 'GUESS' (direction = 5)

switch number

       case 1

            set(handles.pushbutton9,'ForegroundColor','blue');

            set(handles.pushbutton46,'ForegroundColor','black');

            set(handles.pushbutton43,'ForegroundColor','black');

            set(handles.pushbutton49,'ForegroundColor','black');

            set(handles.pushbutton41,'ForegroundColor','black');

            set(handles.pushbutton47,'ForegroundColor','black');

            set(handles.pushbutton44,'ForegroundColor','black');

            set(handles.pushbutton50,'ForegroundColor','black');

            set(handles.pushbutton42,'ForegroundColor','black');

            set(handles.pushbutton48,'ForegroundColor','black');

            set(handles.pushbutton45,'ForegroundColor','black');

            set(handles.pushbutton51,'ForegroundColor','black');

       case 2

......end

switch number

       case 1

            pushbutton9_Callback(hObject, eventdata, handles);

       case 2

            pushbutton46_Callback(hObject, eventdata, handles);

       case 3

            pushbutton43_Callback(hObject, eventdata, handles);

......end

One of the Button Down Callback Function.

function pushbutton9_Callback(hObject, eventdata, handles)

global count color1 color2 green yellow cyan red blue black

count = count + 1;

if count == 1

    set(handles.pushbutton9,'BackgroundColor','green');

    color1 = 1;

else

    set(handles.pushbutton9,'BackgroundColor','green');

    color2 = 1;

    if color1 == color2

        count = 0;

        green = 1;

    else

        count = 0;

end

    pause(1);

    if green == 0

            set(handles.pushbutton9,'BackgroundColor','white');

            set(handles.pushbutton44,'BackgroundColor','white');  end

    if cyan == 0

            set(handles.pushbutton46,'BackgroundColor','white');

            set(handles.pushbutton51,'BackgroundColor','white');  end

    if yellow == 0

            set(handles.pushbutton42,'BackgroundColor','white');

            set(handles.pushbutton50,'BackgroundColor','white');  end

    if red == 0

            set(handles.pushbutton48,'BackgroundColor','white');

            set(handles.pushbutton47,'BackgroundColor','white');  end

    if blue == 0

            set(handles.pushbutton49,'BackgroundColor','white');

            set(handles.pushbutton41,'BackgroundColor','white');  end

    if black == 0

            set(handles.pushbutton43,'BackgroundColor','white');

            set(handles.pushbutton45,'BackgroundColor','white');  end

end

Show the number of guesses.

if green == 1 && cyan == 1 && blue == 1 && yellow == 1 red == 1 && black == 1

   count2 = count2 / 2;

   S = 1;                                      %exit loop

   fprintf('You tried %.0f times.\n', count2); %print out the number of guesses

end
