MPU6050 3D Cube Project Brief
Project Overview
A real-time 3D visualization system that uses an MPU6050 accelerometer to control a 3D cube on screen. The cube rotates in response to physical movements of the sensor.
Hardware Setup
ESP32-C3 + MPU6050
ESP32-C3 (Microcontroller)
MPU6050 (Motion Sensor)
Wiring:
VCC → 3.3V
GND → GND
SDA → GPIO7
SCL → GPIO6
USB → Computer (COM11)
Software Architecture
1. Arduino/ESP32 Code (Data Collection)
// Reads raw accelerometer data
void loop() {
// Reads: ax, ay, az (raw values: -17000 to +17000)
Serial.print(ax); Serial.print(",");
Serial.print(ay); Serial.print(",");
Serial.println(az); // Sends: "123,-456,16384"
}
2. Processing Code (3D Visualization)
java
// Receives data and creates 3D graphics
void serialEvent() {
// Parses: "123,-456,16384" → ax=123, ay=-456, az=16384
}

void draw() {
// Maps MPU data to 3D cube rotation
rotateX = map(ay, -17000, 17000, -PI, PI);
rotateY = map(ax, -17000, 17000, -PI, PI);
// Applies rotation to 3D cube
}

Real-time Cube Rotation
Control Scheme
• Tilt Left/Right → Cube rotates around Y-axis
• Tilt Forward/Back → Cube rotates around X-axis
• Stationary → Cube remains still
• Movement → Direct 1:1 rotation mapping
Key Technical Features
MPU6050 Data Range
• X-axis: -17000 to +17000 (Left to Right tilt)
• Y-axis: -17000 to +17000 (Forward to Back tilt)
• Z-axis: ~16384 (Gravity when flat)
3D Rendering
• P3D Renderer: Hardware-accelerated 3D graphics
• Lighting: Directional + ambient lights
• Cube: 6 colored faces with wireframe
• Real-time: 60fps smooth rotation
Sensitivity Control
java
// Adjust these values:
float deadZone = 100; // Ignore small movements
float sensitivity = 0.001; // Rotation speed
