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

Reason for care:

Because I love anything that simulates

inspiration:

I was a member of the Pixels team on the Projects and Competitions committee and it was my role to search for ideas for simulation-related projects that were not popular, and this idea was the best, most exciting, and least popular on the Internet, so I chose it

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)

My design inspiration video link

I used this design mechanism to make my pedals

Pédale / Pedal / Throttle gas with potentiometer for go kart, ride on, power wheel by stephanemermetI was in need to design a pedal for a speed controller with potentiometer. The need was to have a small footprint (kid car toy), and no specific external component to add. Therefore I design this model, fully functional for me, adapted for standard potentiometer such as 10k ones. The feedback force for the pedal is ensured by a simple clothespin spring. You just need a clothespin and a potentiometer. 4 STL pieces : pedal base pedal top gear and rack to act on the pot 4 axes (3 use +1 if some broke in case of sanding) I print it on an ender 3 pro, infill 50%. It's very small and thin pieces so you may print it with an infill of 100% to make it stronger. At a first glance, you can print it light just to test your potentiometer size. You may need to enlarge with a cutter the axis of the gear to insert your pot in the gear.

and pedal base i used a this website to make it by my own dimensions

my problem in this part was When I press with my feet on it, there is a part that goes down

Therefore, it cannot be completely placed on the ground

We must put a space below it so that it can accommodate this part that goes down

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)

In this video, you can watch design , electronics ,programming , assemply , and fabrication 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)

the input :

potentiometer (for steering angle)
potentiometer (for throttle angle)
limit switch (for brake state)

the action components :

graphical action (control the pc game)

arduino uno board

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)

the USB cable is to communicate with pc

9v adapter to power Arduino

Project Programming

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

the idea of the project is to upload firmware to Arduino that makes it act as a joystick, not as a com port

download the unojoy_zipfile that included in the description and follow the steps in this video to upload the firmware

the code
i added to the UnoJoyArduinoSample that yellow sentence below to add a feature to my project
( make the throttle pedal act as analog not digital )

in the first photo
void setupPins function consists of for loop to set up the pins from 2 to 12 and A4 and A5 as digital input pins

in the second photo
make a joystick button state decision depend on read the state of every input pin that was set up before
read the analog value of A0 and A1 as an input sticks

the wiring

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 have in my project 4 main modules:

(pedals, pedals base, steering wheel, and steering wheel base)

integrate the wheel with the wheel base by potentiometer

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?

ROW'A (fab lab specialist)

One of the most helpful, kind, and skilled people
And she helped me in many stages during the diploma (tasks, documentation, final project, fabrication,...... and more)
All thanks, respect and gratitude to you, ROW'A

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 the potentiometer installing in steering wheel base
my friend Mohamed sorour helped me in this problem and make this part

it was the potentiometer installed in steering wheel

row'a helped me to think about a way to do that
and we edited the steering design to make it have a place to install the potentiometer and printed the part of the potentiometer in the pedal again and used it

Future Work

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

1. I would replace the wheel potentiometer with a rotary encoder to use its internal switch as a horn as a real wheel have
2. and add a dynamic simulation chair to make you feel the moves of the car
3. and a fan to make you feel the air caused by walking and speed
4. and a big stand connects the pedal and the steering wheel instead of just wires
