Hit the

Objective:

To create a video game using a piezo buzzer $($speaker$),$ an OLED I$2$C

display and a joystick with a pushbutton all connected to a microcontroller.

In this game the user will see an $"x"$ appear somewhere at random on the

screen. They will then use the joystick to move a second character on the

screen $($such as a $"0")$ until it covers the $x$ symbol, and push the button. If

the location of both characters is the same, the $x$ then re$-$appears at another

random location and the game continues. After $10x\text{'}$s the game ends and

the user is given a score showing how much time it took him to get $10$ "hits".

Details:

When the game starts there should be an introduction shown on the screen,

and a short tune will play on the speaker. After this the games starts as

described earlier. If the user pushes the button and misses, a short tone

should play. If he "hits the $x",$ a short little tune should play and he gets a

message on the screen such as "you hit it$!.$ Then the $x$ re$-$appears in a

different random place and the game continues. After $10x\text{'}$s the game ends,

and the total time it took the user to get ten hits will be shown as a score.

After this the game restarts.

Hints:

$-$To keep track of the time it took to hit ten x$\text{'}$s $($and generate a score for the

user$)$ you can use the millis$()$ function.

$-$The joystick has a hard time pushing the button if it is moved to the

extremes in either the $x$ or $y$ direction, restrict the $x$ target to a range where

it does not appear at the extremes.

$-$use the Arduino "tone" command to generate sound. Use a short for loop to

create a changing sound, such as a siren.

$-$compare the $x$ and $y$ coordinates of the $x$ and the $0$ to determine a hit when

the button is pressed
