For my last modification I decided that instead of making the game wireless I wanted to choose a more practical modification, like putting all the electronics of the game in a box and making a clean finish. Another part of my last modification was that I added a buzzer sound to the game for every time the button is pressed. In order to do this, I first had to add a connection from pin 3 on the Arduino board to the button and a connection from ground to the button. Next, I had to modify my code. In order to make the buzzer sound every time that the player presses the button, I added an ‘if’ statement. The statement was basically that “if the button was pressed (meaning it was considered false in the code),” then the buzzer would sound with a specific loudness determined by a numerical value in the code. I made these statements for different times when the button is pressed. For example, when the game is first turned on, when the character enters the field, when the player jumps, and when the player hits one of the blocks. All situations required an if statement. The other modification was the box. This was pretty simple, as all I had to do was cut holes in the front of the cardboard for the LCD screen and the two buttons. I also made everything more compact by taking a part of a breadboard off and using it in the box. The helped save a lot of space. One challenge that I faced in the last part of my project was that I was having a lot of trouble making the buzzer go off in different situations in the game. I knew how to make the buzzer sound whenever the button was pressed, I just wasn’t sure how to do it with different situations in the game. I had to use online resources in order to understand how to do this. Another challenge was building the case for the entire game. I learned that it is important to start with a plan and a diagram for how I would build the box because when I didn’t, I ran into many obstacles. Overall I would say that my final project was a success and I had a lot of fun making it.

For my first modification, I decided as a part of the menu screen I would add a difficulty selection. The difficulties could be selected on the menu screen from easy, medium, hard, and impossible. I planned that each of the levels would get increasingly faster as the levels got harder. In order to do this, I had to adjust the code. The first step was to print the choices on the menu screen with a simple print statement for all the levels. As for making the game go faster when a harder level is selected, I had to set 4 different cases for each level in the code. If easy was selected from the menu screen, the delay would be set to 70 milliseconds in the loop. If medium was selected then 50 milliseconds. If hard, then 15 milliseconds. If impossible, then 1 millisecond. I also had to connect a wire from a pin on the Arduino (pin 2) to a button for level selection. The challenges I faced for this 1st milestone was writing code for different difficulty levels. Since this was my first time doing this I had to look online for the basic instructions to do it. It ended up working and being rather simple. As for my project in the future, I plan to make it wireless and have a flush setup where the LCD is in wood and the controller has bigger buttons and can be hand-held comfortably.
