Introduction: Virtual Reality Suit Using Arduino
I have created this project to play normal computer games in full VR . This project emulates your movements into pressing or holding the keys of your keyboard
Example- when you move forward the action of pressing the key 'w' is emulated .
I have emulated the game Call of Duty 4: Modern Warfare but don't choose games that have recoil while shooting because it will change the default position of the mouse
Step 1: Requirements
Requirements are-
There is a list full of things you need to make this suit
Touch sensors-5
Force sensor-1
GPU 6050 - 4
(or)
GPU 6050 - 2 & Accelerometer - 2
Vr glasses
Vr enabled phone
PC
WiFi hotspot
A toy gun
A pc game( i have used Call of Duty- Modern Warfare 1)
Bread board wires (Male-Female )
ARDUINO LEONARDO-2
Auton sheild - 2
Power source (lipo)
Rainbow wires
Step 2: HARDWARE
*reload_pin,shoot_pin,night vision_pin,grenade_pin,weapon change_pin are touch sensors. aim_pin is force sensor and mouse is emulated by MPU6050 other sensors are accelerometer(posture,movement1&2)
1.1) SOLDERING
SOLDER MPU 6050, Accelerometer, Touch Sensor & force sensor with the wires
1.2) WIRING
For MPU 6050-
Pin 2- SDA
Pin 3- SCL
GND - GND
5v - PWR/VCC
For movement_pin1-
Pin A1- x axis
GND-GND
5v - PWR/VCC
For movement_pin2-
Pin A2- x axis
GND-GND
5v - PWR/VCC
For posture_pin-
Pin A0- x axis

for weapon_pin –
sig-5v
GND-GND
5v - PWR/VCC
For Reload_pin –
pin12 – 5v
GND-GND
5v - PWR/VCC
For Nightvision_pin –
pin 10 – 5v
GND-GND
5v - PWR/VCC
For shoot_pin –
Pin7 – 5v
GND-GND
5v - PWR/VCC
For aim_pin –
Pin 8 – 5v
5v - PWR/VCC
1.3)SOLDERING WIRES
Solder the bread board wires with the rainbow wires
1.4) INSULATION
Tape the wires with the insulation tape on the place where you have soldered to avoid short circuits
Step 3: SOFTWARE
I have used an app called 'Remotr' from Play store to cast the video from the laptop to the phone
2.1) REMOTR-
Install REMOTR application to your computer and create an account
Here is the link-
http://remotrapp.com/#download
Install REMOTR app in your smartphone
2.2) VIDEO STREAMING
First connect both the computer and the same WiFi network and enter your REMOTR account in both the devices
now manually add the game which you want to stream in the software
now the app will show the computer as admin click it to start streaming
To stream in VR enable vr mode in your smartphone

Step 4: MAIN CODE
The code for this project is not tough or complex but a long one
Here is the code just copy it and paste it in your arduino file
ARDUINO
LEONARDO Mouse-
I have reffered Gabry295. This mouse code is based on his head Mouse instructable
#include
#include
#include
#include
int aim_pin;
int shoot_pin;
MPU6050 mpu;
int16_t ax, ay, az, gx, gy, gz;
int vx, vy;
void setup() {
Serial.begin(9600);
Mouse.begin();
Wire.begin();
mpu.initialize();
if (!mpu.testConnection()) {
while (1);
}
pinMode(7,INPUT);
pinMode(8,INPUT);
}
void loop() {
shoot_pin = digitalRead(7);
aim_pin = digitalRead(8);
mpu.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);
vx = (gx-300)/200; // I have put -300 and +490 as my mpu6050 show these values when not moving check
vy = -(gz+490)/200; // check the code of head mouse by Gabry295 for more details on these values
Mouse.move(vx, vy);
delay(20);
while(shoot_pin == HIGH);
{
Mouse.click();
}
while(aim_pin == HIGH);
{
Mouse.click();
}
}
Leonardo Keyboard-
#include
int Grenade;
int weapon_pin;
int reload_pin;
int movement1_pin;
int movement2_pin;
int posture_pin;
char nightvision_pin;
void setup()
{
pinMode(7,INPUT);
pinMode(8,INPUT);
pinMode(9,INPUT);
pinMode(10,INPUT);
pinMode(11,INPUT);
pinMode(12,INPUT);
pinMode(A0,INPUT);
pinMode(A1,INPUT);
Keyboard.begin();
}
void loop()
{
Grenade_pin=digitalRead(8);
weapon_pin = digitalRead(9);
movement1_pin = analogRead(A1);
movement2_pin = analogRead(A2);
posture_pin = analogRead(A0);
reload_pin = digitalRead(12);
nightvision_pin = digitalRead(10);
if(grenade==HIGH)
{
Keyboard.press('g');
}
while (weapon_pin == HIGH)
{
Keyboard.press('q');
}
while(reload_pin == HIGH)
{
Keyboard.press('r');
}
while (movement1_pin>340&&movement1_pin<420)
{
Keyboard.press('w');
}
while (movement1_pin>420)
{
Keyboard.press('w');
Keyboard.press('p');
}
while (movement2_pin>340&&movement2_pin<420)
{
Keyboard.press('w');
}
while (movement2_pin>420)
{
Keyboard.press('p');
Keyboard.press('w');
}
while (posture_pin>340&&posture_pin<420)
{
Keyboard.press('c');
}
while (posture_pin>420)
{
Keyboard.press('l');
}
while (posture_pin<340)
{
Keyboard.press('z');
}
while (nightvision_pin==HIGH)
{
Keyboard.press('n');
}
}
}
Step 5: TEST CODES
Here are the few codes divided from the main code according to the
function
SHOOTING-
#include
int x;
void setup() {
pinMode(8,INPUT);
Mouse.begin();
}
void loop() {
x=digitalRead(8);
if(x==HIGH)
{
Mouse.click('g’);
}
}
AIMING-
#include
#include
#include
#include
MPU6050 mpu;
int16_t ax, ay, az, gx, gy, gz;
int vx, vy;
void setup() {
Serial.begin(9600);
Mouse.begin();
Wire.begin();
mpu.initialize();
if (!mpu.testConnection()) {
while (1);
}
}
void loop() {
shoot_pin = digitalRead(7);
aim_pin = digitalRead(8);
mpu.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);
vx = (gx+300)/200; // "+300" because the x axis of gyroscope give values about -350 while it's not moving. Change this value if you get something different using the TEST code, chacking if there are values far from zero.
vy = -(gz_-100)/200; // same here about "-100"
RELOADING-
#include
int x;
void setup() {
pinMode(8,INPUT);
Keyboard.begin();
}
void loop() {
x=digitalRead(8);
if(x==HIGH)
{
Keyboard.press('r');
}
else
{
Keyboard.release('r');
}
}
NIGHT VISIO #include
int x;
void setup() {
pinMode(8,INPUT);
Keyboard.begin();
}
void loop() {
x=digitalRead(8);
if(x==HIGH)
{
Keyboard.press('g’);
}
else
{
Keyboard.release('g');
}
}
CROUCH AND PRONE-
#include
int y;
void setup() {
pinMode(A0,INPUT);
Serial.begin(9600);
}
void loop() {
y=analogRead(A0);
if(y<260)
{
Keyboard.release('c');
Keyboard.release('p');
}
else if(y>260&&y<310)
{
Keyboard.press('c');
}
else if(y>310)
{
Keyboard.press('p');
}
}
Step 6: GAME CONTROLS
change the game controls as follows
crouch - x
prone - l
weapon change - q
sprint - p
stand/jump - z
night vision - n
forward movement - w
grenade - g
Step 7: SETTING UP
Finally we have come to the last step now put the arduino
boards in a box and slip it into the bag
Now connect the micro USB of the arduino to the USB ports of laptop now connect the sensors as directed above
*arrow marks in the above pictures represents the direction the sensor must face
If you have any doubts don't hesitate to leave a comment and don't forget to share your experience
That's it thank you and
