Summary

This circuit utilizes an Arduino UNO microcontroller to control two DC motors through an L298N DC motor driver. The power supply is provided by a battery pack consisting of two 18650 lithium-ion cells. The Arduino communicates with the motor driver to control the speed and direction of the motors.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
• Purpose: Acts as the main control unit for the circuit, sending signals to the motor driver to control the motors.

L298N DC Motor Driver

• Description: A dual H-bridge motor driver that can control the direction and speed of two DC motors.
• Purpose: Interfaces between the Arduino and the DC motors, allowing for control of motor direction and speed.

2x 18650 Lithium-Ion Battery

• Description: A rechargeable lithium-ion battery pack.
• Purpose: Provides the necessary power supply for the circuit.

DC Motor (x2)

• Description: Standard DC motors used for driving wheels or other mechanical components.
• Purpose: Perform the mechanical work as directed by the motor driver.
