Arduino Vr

Hi My name is Christian and I'm 13 years old. I love arduino and have a talent for it so here is my instructable for an arduino vr.

Supplies

Supplies:

1. Arduino board Mega, Due, Uno, or Yun.

2. Male to male (standard jumper wires) wires.

3. Small breadboard

4. USB

5. GY-521 MPU-6050

Optional:

6. 5.5 inch 2560*1440 2K LCD Screen HDMI to MIPI

7. Fresnel lens Focal Length 50mm

8. 3-D printer or 3d printer service

Step 1: Assemble

Use the schematic to put it together.

Step 2: ​How to Install Library?

Have a look at the Github: https://github.com/relativty/Relativ You can either install it using Git or direct Download.

Step 3: Code

// i2cdevlib and MPU6050 are needed: https://github.com/jrowberg/i2cdevlib

// Big thanks to the amazing Jeff Rowberg <3, go check his repo to learn more MPU6050. //=============================================================================

// I2Cdev and MPU6050 must be installed as libraries, or else the .cpp/.h files // for both classes must be in the include path of your project

#include "Relativ.h"

#include "I2Cdev.h"

#include "MPU6050_6Axis_MotionApps20.h"

#if I2CDEV_IMPLEMENTATION == I2CDEV_ARDUINO_WIRE #include "Wire.h" #endif

MPU6050 mpu; Relativ relativ;

#define INTERRUPT_PIN 2

// IMU status and control: bool dmpReady = false; // true if DMP init was successful uint8_t mpuIntStatus; uint8_t devStatus; // 0 = success, !0 = error uint16_t packetSize; uint16_t fifoCount; uint8_t fifoBuffer[64];

Quaternion q; // [w, x, y, z]

volatile bool mpuInterrupt = false; // indicates whether MPU interrupt pin has gone high void dmpDataReady() { mpuInterrupt = true; }

void setup() { #if I2CDEV_IMPLEMENTATION == I2CDEV_ARDUINO_WIRE Wire.begin(); Wire.setClock(400000); // 400kHz I2C clock. Comment this line if having compilation difficulties #elif I2CDEV_IMPLEMENTATION == I2CDEV_BUILTIN_FASTWIRE Fastwire::setup(400, true); #endif

relativ.startNative(); // "startNative" can be used for 32-bit ARM core microcontroller with Native USB like Arduino DUE // which is recommended. // Relativ.start(); // "start" is for NON-NATIVE USB microcontroller, like Arduino MEGA, Arduino UNO.. // Those are significantly slower. mpu.initialize(); pinMode(INTERRUPT_PIN, INPUT);

SerialUSB.println(mpu.testConnection() ? F("MPU6050 connection successful") : F("MPU6050 connection failed"));

// configure the DMP devStatus = mpu.dmpInitialize();

// ================================== // supply your own gyro offsets here: // ================================== mpu.setXGyroOffset(220); mpu.setYGyroOffset(76); mpu.setZGyroOffset(-85); mpu.setZAccelOffset(1788);

// devSTatus if everything worked properly if (devStatus == 0) { // turn on the DMP, now that it's ready mpu.setDMPEnabled(true);

// enable Arduino interrupt detection attachInterrupt(digitalPinToInterrupt(INTERRUPT_PIN), dmpDataReady, RISING); mpuIntStatus = mpu.getIntStatus();

dmpReady = true;

// get expected DMP packet size for later comparison packetSize = mpu.dmpGetFIFOPacketSize(); } else { // ERROR! } }

void loop() { // Do nothing if DMP doesn't initialize correctly if (!dmpReady) return;

// wait for MPU interrupt or extra packet(s) to be available while (!mpuInterrupt && fifoCount < packetSize) { }

// reset interrupt flag and get INT_STATUS byte mpuInterrupt = false; mpuIntStatus = mpu.getIntStatus();

// get current FIFO count fifoCount = mpu.getFIFOCount();

if ((mpuIntStatus & 0x10) || fifoCount == 1024) { mpu.resetFIFO(); } // check for interrupt else if (mpuIntStatus & 0x02) { while (fifoCount < packetSize) fifoCount = mpu.getFIFOCount(); mpu.getFIFOBytes(fifoBuffer, packetSize); fifoCount -= packetSize; mpu.dmpGetQuaternion(&q, fifoBuffer); relativ.updateOrientationNative(q.x, q.y, q.z, q.w, 4); // updateOrientationNative" can be used for 32-bit ARM core microcontroller with Native USB like Arduino DUE // which is recommended. //relativ.updateOrientation(q.x, q.y, q.z, q.w, 4); // Relativ.updateOrientation" is for NON-NATIVE USB microcontroller, like Arduino MEGA, Arduino UNO.. // Those are significantly slower. } }

Step 4: Play

moving the small breadboard on any vr game should rotate the camera
