Summary

This circuit integrates a microcontroller, sensors, communication modules, power management, and motor control components to create a system capable of interfacing with a Bluetooth module and MPU-6050 sensor, driving multiple coreless motors, and managing power through a boost converter. The Arduino Pro Mini serves as the central processing unit, interfacing with the HC-05 Bluetooth Module for wireless communication and the MPU-6050 for motion tracking. The boost converter MT3608 steps up the voltage from a LiPo battery to power the system, and MOSFETs, in conjunction with resistors, control the coreless motors.
