Summary of the Circuit
This circuit is designed to control a set of four "Motor amarillo motorreductor hobby" DC motors using an Arduino UNO microcontroller and an L298N DC motor driver. The Arduino UNO is responsible for generating control signals that are sent to the L298N driver, which in turn drives the motors. The power for the circuit is provided by a pair of 18650 Li-ion batteries connected in series or parallel (not specified in the net list), which supply power to both the Arduino and the motor driver.
Component List
Arduino UNO
