Gaming Steering Wheel
A gaming steering wheel which control a car game and PC race gaming
I was inspired by the Steering wheel controller from childhood, So I decided to make it by myself to be as possible as the real one.
It will control the direction, speed and lights of the car, So I searched for the best car which I can make until I saw a Tesla car model, then I started to make it.

Inside Design
Front Design
First i sketch a circuit and another smaller one with rectangle in the center then after adding the electrical components, I use extrude cut tool to edit the main front sketch.
Back Design
The same as the front sketch, I sketch a circle and another with the same dimension then extrude cut after adding the another parts and joints.
Wheel Stand
The function of wheel stand is to make the wheel fixed and stable on the table so as there is no standard dimensions for the table , I sketch many holes to change the height level to be fixed as possible as.
Main Joint Point
To read angle from steering wheel, The Stand must be fixed on the table then we can change the angle of the steering by change and the value of the potentiometer.
Back Buttons
To achieve the best experience for the user, I added two back limit switches to control the speed and brake of the car.
Inside Design
Here, I added the needed components for main functions and then extrude cut the required joints.

Components
Arduino UNO for control the circuit and run the code.
Bluetooth module HC-05 for communication between steering and car.
Yellow motor to move the tesla car.
Mini Breadboard to wiring the circuit.

Software

Inputs & Actions description
At the steering wheel,
The Arduino reads the state of gas and brake input from the player.
Also, it measures the analog value of the potentiometer as its the angle of the steering.
Also, it reads the reverse state input from the player.
The Arduino does some processing on the inputs to create a string variable that contains the speed value of the right and left motors.
The Arduino sends the string by Bluetooth serial to the car to control it.
At the Tesla car,
The Arduino receives the data string from the steering wheel.
The Arduino reads the values of motors from the string.
Then, It applies the value to the motor driver to control the car depending on the steering inputs.

Steering wheel
For the steering wheel, I designed it to contain two ways for powering, The USB cable and the 5v adapter.
The main power source is the USB cable to connect Arduino to the laptop as the steering can control pc games.
Tesla car
For the Tesla car, I designed it to be powered using a 5V, 2A power bank as the car must be powered wireless and the motors need 2A to start the movement.

Master & Slave Configuration
The main purpose of the code is to config the Bluetooth module in the steering wheel to connect automatically with the Bluetooth module in the tesla car.
Implementation Steps
Include "softwareSerial" library.
Create an object and pass to it the RX and TX pins of the Bluetooth.
Connect the key pin to high voltage to switch to AT mode.
In setup fun, Pass the default speed of Bluetooth (38400) to the initialization function of the Bluetooth module.
In loop fun, Use "serial.available" fun to read from Arduino serial then write the input string in Bluetooth serial by using "object.write" fun.
Check the Bluetooth serial also then read the output by using "serial.write" fun.
Slave At commands
AT+RMAAD (To clear any paired devices).
AT+ROLE=0 (To set it as a slave).
AT+ADDR (To get the address of this HC-05, remember to jot the address down as it will be used during master configuration).

Master At commands
AT+RMAAD (To clear any paired devices)
AT+ROLE=1 (To set it as master)
AT+CMODE=0 (To connect the module to the specified Bluetooth address and this Bluetooth address can be specified by the binding command)

AT+UART=38400,0,0 (To fix the baud rate at 38400)

Design Problems
The source design of tesla was in cdr format so I searched for Coreldraw software tutorials to learn how to deal with tesla's sketch parts.
The Tesla sketches after extruding it from Coreldraw can not be extruded as they weren't fully closed, SoI searched for a solution then I found this tutorial on YouTube that helped me to fix this problem by using a line and then changing its position until an area is created.
Software Problems
I faced a problem during changing the configuration of the master and slave Bluetooth modules, So I searched about it and found documentation that helped me to config the module correctly.
