Summary

This circuit is designed to control two motors with reducers using an L298N DC motor driver, which is interfaced with an Arduino UNO microcontroller. The circuit also includes multiple infrared (IR) sensors for input and a rocker switch (SPST) to control the power supply. The power supply is a 7.4V battery. The Arduino UNO is responsible for processing the signals from the IR sensors and controlling the motor driver, which in turn controls the motors.

Wiring Details

Arduino UNO

• 5V and GND pins are used to power the IR sensors and the L298N motor driver.
• Digital pins D2 to D12 are used to interface with the IR sensors and the L298N motor driver.

Motor with Reducer

• Each motor is connected to the L298N motor driver's output pins (OUT1, OUT2, OUT3, OUT4).

L298N DC Motor Driver

• 5V pin is connected to the IR sensors and the Arduino's 5V pin.
• GND pin is connected to the IR sensors, the Arduino's GND pin, and one side of the rocker switch.
• IN1 to IN4 pins are connected to the Arduino's digital pins D7 to D10 for motor control signals.
• ENA and ENB pins are connected to the Arduino's digital pins D6 and D5 for enabling the motor driver.
• OUT1 to OUT4 pins are connected to the motors.
• 12V pin is connected to the 7.4V battery's positive terminal.

Rocker Switch (SPST)

• One pin is connected to the 7.4V battery's negative terminal.
• The other pin is connected to the L298N motor driver's GND.

IR Sensors
