📖 Quick Start Guide

Setup Steps

Upload the Arduino code below to your board

Wire MPU6050 → SDA→A4, SCL→A5, VCC→3.3V, GND→GND

Click Connect to MPU6050 and pick the COM port

Tilt the sensor — the 3D arm moves in real time

Use sliders manually when sensor is not connected

Arduino sketch — MPU6050

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

MPU6050 mpu;

void setup() {
  Serial.begin(115200);
  Wire.begin();
  mpu.initialize();

  if (!mpu.testConnection()) {
    Serial.println("MPU6050 failed");
    while(1);
  }
}

void loop() {
  int16_t ax, ay, az, gx, gy, gz;
  mpu.getMotion6(&ax, &ay, &az,
                 &gx, &gy, &gz);

  // Convert raw data to angles
  float roll  = atan2(ay, az) * 180.0 / PI;
  float pitch = atan2(-ax,
    sqrt((float)ay*ay + (float)az*az))
    * 180.0 / PI;
  float yaw   = gz / 131.0;

  // Clamp to simulator ranges
  yaw   = constrain(yaw,   -180, 180);
  pitch = constrain(pitch,  -90,  90);
  roll  = constrain(roll,  -180, 180);

  // Send in required format
  Serial.print("DATA:");
  Serial.print(yaw,   1);
  Serial.print(",");
  Serial.print(pitch, 1);
  Serial.print(",");
  Serial.println(roll, 1);

  delay(50); // 20 Hz
}

💡 Any sensor works — just send DATA:v1,v2,v3 at 115200 baud. Works with joysticks, flex sensors, ultrasonic, potentiometers, and more. Requires Chrome or Edge.
