Circuit Documentation

Summary

This circuit is designed to control a set of four "Motor amarillo motorreductor hobby" motors using an "Arduino UNO" microcontroller and an "L298N DC motor driver". The circuit also includes an "HC-05 Bluetooth Module" for wireless communication and a set of LEDs for indication purposes. The power is supplied by a "battery 12v". The Arduino UNO is programmed to manage the motor driver, read signals from the Bluetooth module, and control the LEDs.

Component List

Motors

• Motor amarillo motorreductor hobby: A hobbyist DC gear motor that requires a power supply and ground connection.

Microcontroller

• Arduino UNO: A microcontroller board based on the ATmega328P, equipped with a variety of digital and analog I/O pins.

Motor Driver

• L298N DC motor driver: A dual H-bridge motor driver capable of driving two DC motors or one stepper motor.

Power Supply

• battery 12v: A 12-volt battery providing the main power source for the motor driver and indirectly for other components through voltage regulation.

Wiring Details

Motors

• Motor amarillo motorreductor hobby: Each motor's vcc and GND pins are connected to the corresponding output pins OUT1, OUT2, OUT3, and OUT4 of the L298N motor driver.

Arduino UNO

• Digital pins D13, D12, D11, and D10 are connected to the anodes of the red and white LEDs.
• Digital pins D9, D8, D7, D5, D4, and D3 are connected to the ENA, IN1, IN2, IN3, IN4, and ENB pins of the L298N motor driver, respectively.
• Digital pins D1 and D0 are used for serial communication with the HC-05 Bluetooth module's RXD and TXD pins.
• The 5V pin provides power to the HC-05 Bluetooth module.
• The GND pin is connected to the common ground net, which includes the cathodes of the LEDs and the ground of the HC-05 Bluetooth module.

L298N DC motor driver

• The 12V pin is connected to the positive terminal of the 12v battery.
• The GND pin is connected to the negative terminal of the 12v battery and the common ground net.

HC-05 Bluetooth Module

• The VCC pin is connected to the 5V output from the Arduino UNO.
• The GND pin is connected to the common ground net.

LEDs

• The anodes of the red and white LEDs are connected to their respective Arduino UNO digital pins for control.
• The cathodes of all LEDs are connected to the common ground net.

Documented Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

The provided code is a template with empty setup() and loop() functions. The setup() function is intended for initialization code that runs once at startup, and the loop() function contains the main logic of the program that runs repeatedly. Actual implementation details need to be added to control the motors, read from the Bluetooth module, and manage the LEDs.
