Arduino Steering Wheel Simulator for gaming

 

You want an Arduino Steering Wheel Simulator for gaming. This project will let you use an Arduino as a USB steering wheel for PC games. It will use a potentiometer to detect steering rotation and send data via USB as a joystick. 🎮🕹️

Components Required:

• Arduino Leonardo or Arduino Micro (supports USB HID)

• Rotary Potentiometer (10kΩ) (for steering input)

• Push Button (for extra controls like horn, brake, etc.)

• Jumper Wires

Circuit Diagram

Connections:

• Potentiometer

  • Middle pin → A0 (Analog Input)

  • One side → 5V

  • Other side → GND

• Push Button (Optional)

  • One pin → D2

  • Other pin → GND

I'll generate a circuit diagram for you in a moment. Meanwhile, here’s the code.

💻 Arduino Code for USB Steering Wheel

#include <Joystick.h>  // HID Library for joystick support

Joystick_ Joystick(JOYSTICK_DEFAULT_REPORT_ID, JOYSTICK_TYPE_GAMEPAD,
                   1, 0,  // 1 button, no hat switch
                   true, false, false,  // X, Y, Z Axis
                   false, false, false,  // Rx, Ry, Rz
                   false, false,  // Rudder, Throttle
                   false, false, false); // No extra axes

const int potPin = A0;  // Potentiometer for steering
const int buttonPin = 2; // Optional button for action

void setup() {
  pinMode(buttonPin, INPUT_PULLUP);  // Pull-up to avoid floating input
  Joystick.begin();
}

void loop() {
  int potValue = analogRead(potPin);  // Read potentiometer
  int steeringValue = map(potValue, 0, 1023, -127, 127); // Convert to joystick range
  Joystick.setXAxis(steeringValue);  // Send steering input

  int buttonState = digitalRead(buttonPin);
  Joystick.setButton(0, buttonState == LOW);  // Button press

  delay(10);  // Small delay for stability
}

✅ How it works:

• The potentiometer acts as a steering wheel by converting rotation into joystick X-axis movement.

• The button can be mapped to any in-game function (like honking).

• The Arduino Leonardo/Micro appears as a game controller when connected to a PC.
