Circuit Documentation

Summary

This circuit integrates an Arduino Nano microcontroller with a Motor Driver 1A Dual TB6612FNG to control two DC gearmotors. A step-down buck converter is used to regulate the voltage supplied by a LiPo battery to the appropriate levels for the Arduino and the motor driver. The Arduino Nano is programmed to interface with the motor driver, which in turn drives the gearmotors based on the signals received from the Arduino.
