This circuit features a Nucleo 401RE microcontroller as the central processing unit, interfacing with an ADXL345 accelerometer and an INA219 current sensor over an I2C bus for motion sensing and power monitoring, respectively. A DC motor with an encoder is driven by an L298N motor driver, with speed control potentially provided by a connected potentiometer and vibration feedback through a vibration motor. The system is powered by a 12V battery, with voltage regulation provided for the various components.
