⚙️ Working Principle
The MPU-6050 uses MEMS (Micro-Electro-Mechanical Systems) technology.
Step-by-Step Operation
1️⃣ The accelerometer measures linear acceleration along X, Y, Z axes.
2️⃣ The gyroscope measures rotational velocity around the axes.
3️⃣ The internal Digital Motion Processor (DMP) processes motion data.
4️⃣ Processed data is transmitted to the microcontroller via I²C communication.
5️⃣ The microcontroller calculates orientation, tilt, and motion patterns.
