Final Project Journal

“Maze” is a game that constitutes two roofless boxes of two different sizes, the bigger of which has no base. They both hang on double stands fixed on a rectangular base on parallel sides where they are within each other as shown in the picture. One servo is attached to the larger box at one of the sides connected to the stands, while another servo is attached to the free wide side of the smaller box (maze box). Two screws hold the two boxes together at the other free wide side and the other fixed side.

The “Maze” is controlled by a joystick that moves one of the servos in the x-axis and the other in the y-axis respectively. This double movement navigates the ball inside the maze through the designed path, along which three touch sensors are placed. Two of those touch sensors would light up in red and let out an alarming sound indicating straying away from the right path, while the third at the end of the path lights up in green to indicate making it successfully to the end.

5 V adapter for Servos and 9 V adapter for Arduino.

because the servos I use it need a 5 v power Source, and the other components will take the power from Arduino which will take the power from 9 V adapter

My project is a maze game, controlled by a joystick to move the two servos on the x-axis and y-axis, one of them fix the side part of the base to the center box, and the other one links the center box to the maze box.

On the other two sides, there are no servos, there are two screws to fix the design.

there is a small metal ball that moves when I change the angle of two servos by joystick, the ball has a bath that should go throw it to finish and win the maze, and throw this path there are three touch sensors, two of them were wrong when the ball touch it the led will light red and the buzzer will make a sound which means there is something wrong happen, and the last one is the right touch sensor 'the end of the path' when the ball touch it the led will light with green light and make a specific sound and it will last more than the red one.

-In the beginning, I used the Laser cut maze design generator to fabricate the maze, then I faced a problem with scaling the size of the maze the dimensions of the maze were not correct as I used the floor and wall way, but according to the advice of my mentor (Eng. Ahmed), I changed the way to a single sheet and I used another website ’Maze Generator’

-It was my first time using the joystick, so I was not able to understand how it works and its mechanism, until I received help from my mentor (Eng. Ahmed) and my college (Sharqawy).

-After I fabricated the Arduino box, I could not put it all together according to this I thought there was a problem with the dimensions, so I started to check the whole dimensions on Fusion, but I could not figure out the problem, later on, I figured out that the problem was in how I get it all together by the help of (Eng. Amaal )from Fab Lab team

In the circuit of the touch sensor and the 8-bit led, I was trying to write a code which makes the green/red light turns on upon touching the sensor and the led will not work if nothing touches the sensor but it did not work at the beginning, I tried to add and remove different lines in the code but it did not work then I have searched for different functions that might help in making the touch sensor works as mentioned before , later on I figured out the problem that I wrote if condition within a while loop so it never gets back to else so removing while from the code was the solution

Using the ‘’Maze generator ‘’ did not give the full control of the dimensions the way the other website does so at the beginning it was challenging and I tried to make it on a small scale first to identify thinking of the lines in the design as I could not understand it well from the design, after the fabrication I understand how it works so I started making a new design in the maze generator then I downloaded it and I made it with an offset to make the thickness of lines 6 mm.
