Final Project Journal

Project Ideation

1- Tell us about the idea of your project. Why do you care about this? What were you inspired by? Include images and videos of similar projects

I am a person who loves games and my first start in this field was the snake game. This makes me nostalgic for the past

Inspired by my childhood, playing snake on my Nokia Mobile

Snake Game has been very popular since the beginning of Mobile phones. Initially, it came in Black and white cell phones and soon became very famous.

Project Construction

2- Explain the CAD process of your project. How did you use the software to design your project? (List the softwares/tools/materials...etc that you used)

On the first day of makers diploma, I was fascinated by the design of GameKit and I wanted to know how it was designed.

so my design is kinda similar to the game kit.

Fusion 360 to make the sketches and the whole design

I started with the top side because the rest of the parts depend on it.

The square helped me to make the distances between the pushbuttons equal.

I took the LCD dimensions and draw a rectangle that fits the LCD area and placed it in the middle of the rectangle.

The bot side same as the top side without the LCD and pushbuttons.

so I copied the top side and deleted the LCD and pushbuttons holes.

The left side was kinda easy just a regular rectangular with fits and T-slot.

The other side is the same except the data cable and power hole for the Arduino.

Coming to the easiest part, which is the front and back side.

The left side is the same as the right side so I copied the part which i draw.

My final sketch

Then I extrude my sketch to make it 3D with 3.2 hight.

I assembled all the parts together with joints and then added wood theme to make it more real

3- Explain the fabrication process of your project. How did you use the machine to fabricate your project? (List the softwares/tools/materials...etc that you used)

Laser cutter machine to cut MDF

Laser cad for review send design to machine

3.2mm MDF

First thing in this process I imported all the DXF files in laser cad and make it fit the sheet,I used MDF and the cut parameters were

70 power and 20 speed

Put the MDF sheet, make sure of focus, download the file to the laser cut machine and set up the origin and start the process.

Project Electronics & Power Management

4- Describe your electronic circuit. What are the input and action components? What is the function of each? How do the components integrate together to form your smart system? (List the softwares/tools/components...etc that you used)

I used 4 pushbuttons to control the snake directions up down right and left

with 20 pins

arduino ide for uploading the code on the board.

Jumbers to wire all components

10k potentiometer for lcd contrasts

circuit schematic
/*

PIN-1 : Ground connect to ground terminal of Arduino board

PIN-2 : +5V supply connect to +5V

PIN-3 : V0c is connect to 10k Variable Potentiometer for contrast control

PIN-4 : DI – Data Input pin is connect to Analog pin of Arduino (A3)

PIN-5 : R/W – Read-write pin is connect to Analog pin of Arduino (A2)

PIN-6-: E – Enable pin is connect to Analog pin of Arduino (A4)

PIN-7-14 : DB0-DB7 are connect to Digital pin of Arduino like- 8,9,10,11,4,5,6,7

PIN15 -16 : CS1-CS2 serial communication pins are connect to Analog pin of Arduino( A0-A1))

PIN17 – RESET

PIN18- : pot

PIN19- : A + for 5V Supply

PIN20- : K for Ground

5- What is your power source? How did you select the suitable power source for your project? (List the softwares/tools/components...etc that you used)

I used a 9v adapter to run my hole circuit

9V DC adapter

Project Programming

6- Describe the code of your project. How did you program each function of the project?

I included the library for my screen and set the correct connections in my code as a comment.

I defined the pins of the pushbutton.

My snake can move in four directions so I start to make statements that can determine in which direction the snake will move.

And based on the specific direction, the snake will be moved in that direction

The function of this two functions is to draw the snake's body and food.

This function is interested in knowing if the snake ate food, ate itself, or hit the wall.

If the food is eaten, the spawn food is called.

if the snake ate itself or hit the wall, game over function is called

This function is responsible for eating snakes and it appears in a random place using a random function.

When game over status is true this function will be called and print Game Over on the LCD.

Defining the controlling pins as an input.

And my setup part was just to call the functions.

Project Integration & Testing

7- Demonstrate with text and visuals how did you integrate the project’s modules together? What are the testing results? (Include a Demo video separately, showing a proof of functionality)

I tried to make my game on a small LCD before receiving my final project components.

22.mp4

First of all, I soldered the LCD in the lab with female pin header

After receiving the LCD, I tested it and connected it, and figured out how it works.

There was a lot of wire but I was able to deal with it.

I started to check my LCD and try to connect it and make sure that my LCD is working.

Using 4 small push buttons and I started my game.

hello 4.mp4

I started by attaching the Arduino on the bot side and attached the LCD and push buttons on the top side.

Then I connected the LCD and push buttons to the Arduino and before assembling it checked my circuit.

And after I make sure that my LCD and the code working as I want, I started to assemble my parts.

With Adapter-1-1.m4v

Sharing & Collaboration

8- Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

When I asked my teammates about what my design looked like after I assembled it, they told me you could write something on that side, like engrave the game kit name on the side of the GameKit.

Overcoming Challenges

9- When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this project?

It was my first time dealing with LCD like this and it was challenging for me because the LCD has 20 pins and I have to connect all of them at the same time and it was hard to get a library for my LCD model because it is not popular so I used another library for another model but it worked on it.

I searched about my LCD model and downloaded a data sheet (here) to know what is the functionality of each pin because there was no writing on the screen.

I searched a lot to know how to deal with this LCD, and I found this site that gives me the wiring of the LCD after the LCD worked, and my first test to write Hell World! on the LCD, I start to write my game code after the test.

Also, I didn't receive my 128x64 LCD so I tried to make my game on a small LCD add it was so fun.

Future Work

10- If you had more time, what is one thing you would change/ Do next in your project?

I would like to add more games to my game kit.

so I want to add a menu from which you can choose which game you like to play when you run the game kit.
