Virtual reality (VR) is a technology that has gained significant popularity in recent years. It offers a simulated experience that can be similar to or completely different from the real world. VR has found applications in various industries, including gaming, education, healthcare, and architecture. This article aims to provide an introduction to virtual reality technology and its potential uses.

Project: Creating a Virtual Reality Environment

In this project, we will create a simple virtual reality environment using Arduino and compatible components. The objective is to demonstrate the basic principles of VR and how it can be implemented using Arduino.

List of Components:

• Arduino Uno: 1x (https://store.arduino.cc/arduino-uno-rev3)
• MPU-6050 Gyroscope and Accelerometer Module: 1x (https://www.sparkfun.com/products/11028)
• OLED Display Module: 1x (https://www.adafruit.com/product/938)
• Breadboard: 1x (https://www.sparkfun.com/products/12615)
• Jumper Wires: Assorted (https://www.sparkfun.com/products/12794)

Examples:

Example 1: Reading Gyroscope and Accelerometer Data

#include <Wire.h>
#include <MPU6050.h>

MPU6050 mpu;

void setup() {
  Wire.begin();
  mpu.initialize();
  Serial.begin(9600);
}

void loop() {
  mpu.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);

  Serial.print("Accelerometer: ");
  Serial.print(ax);
  Serial.print(", ");
  Serial.print(ay);
  Serial.print(", ");
  Serial.println(az);

  Serial.print("Gyroscope: ");
  Serial.print(gx);
  Serial.print(", ");
  Serial.print(gy);
  Serial.print(", ");
  Serial.println(gz);

  delay(1000);
}

Example 2: Displaying Data on OLED

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#define OLED_ADDR 0x3C
Adafruit_SSD1306 display(128, 64, &Wire, OLED_ADDR);

void setup() {
  display.begin(SSD1306_SWITCHCAPVCC, OLED_ADDR);
  display.clearDisplay();
  display.setTextSize(1);
  display.setTextColor(WHITE);
  display.setCursor(0, 0);
}

void loop() {
  display.clearDisplay();
  display.setCursor(0, 0);
  display.println("Accelerometer Data:");
  display.println("X: 0.5");
  display.println("Y: -0.2");
  display.println("Z: 0.9");
  display.display();
  delay(1000);
}
