Circuit Documentation

Summary

This circuit integrates an Arduino Nano microcontroller with various peripherals including an HC-05 Bluetooth module, two MPU6050 Accelerometer + Gyroscope sensors, three potentiometers, a red LED, a rocker switch, and several resistors. The Arduino Nano serves as the central processing unit, interfacing with the sensors and modules to perform data acquisition and wireless communication. The potentiometers are likely used for input control or calibration, while the LED provides a visual output. The rocker switch may serve as a power switch or mode selector. The resistors are used for current limiting and pull-up/pull-down configurations.
