L298 2A Dual Motor Driver Module with PWM Control Pinout Explanation
The L298 2A Dual Motor Driver Module with PWM Control is a popular and versatile motor driver module used to control two DC motors simultaneously. It features PWM (Pulse Width Modulation) control for speed regulation and direction control for each motor. Here's a detailed explanation of each pin on the module:
Pinout Structure:
The L298 module has a total of 16 pins, arranged in two rows of 8 pins each. The pins are labeled on the module as follows:
Upper Row ( Pins 1-8 ):
1. VIN (Input Voltage): This pin is connected to the positive terminal of the power supply (typically 5V to 24V). It provides power to the module.
2. GND (Ground): This pin is connected to the negative terminal of the power supply and serves as a common ground for the module.
3. ENA (Enable A): This pin is used to enable or disable Motor A. When set high (5V), Motor A is enabled. When set low (0V), Motor A is disabled.
4. IN1 (Input 1): This pin controls the direction of Motor A. When set high (5V), Motor A rotates clockwise. When set low (0V), Motor A rotates counterclockwise.
5. IN2 (Input 2): This pin controls the direction of Motor A. When set high (5V), Motor A rotates counterclockwise. When set low (0V), Motor A rotates clockwise.
6. OUT1 (Output 1): This pin is connected to one terminal of Motor A.
7. OUT2 (Output 2): This pin is connected to the other terminal of Motor A.
8. PWMA (PWM A): This pin is used to control the speed of Motor A using PWM signals.
Lower Row (Pins 9-16):
9. ENB (Enable B): This pin is used to enable or disable Motor B. When set high (5V), Motor B is enabled. When set low (0V), Motor B is disabled.
10. IN3 (Input 3): This pin controls the direction of Motor B. When set high (5V), Motor B rotates clockwise. When set low (0V), Motor B rotates counterclockwise.
11. IN4 (Input 4): This pin controls the direction of Motor B. When set high (5V), Motor B rotates counterclockwise. When set low (0V), Motor B rotates clockwise.
12. OUT3 (Output 3): This pin is connected to one terminal of Motor B.
13. OUT4 (Output 4): This pin is connected to the other terminal of Motor B.
14. PWMB (PWM B): This pin is used to control the speed of Motor B using PWM signals.
15. VCC (Logic Voltage): This pin is connected to the positive terminal of the logic voltage supply (typically 5V). It powers the module's internal logic.
16. GND (Ground): This pin is connected to the negative terminal of the logic voltage supply and serves as a common ground for the module.
Connection Structure:
To connect the pins, follow this structure:
Connect the power supply to the VIN and GND pins.
Connect Motor A to the OUT1 and OUT2 pins.
Connect Motor B to the OUT3 and OUT4 pins.
Connect the enable pins (ENA and ENB) to a digital output on your microcontroller or a switch to enable or disable the motors.
Connect the direction control pins (IN1, IN2, IN3, and IN4) to digital outputs on your microcontroller to control the motor direction.
Connect the PWM control pins (PWMA and PWMB) to PWM-capable outputs on your microcontroller to control the motor speed using PWM signals.
Remember to consult the datasheet and specifications of the L298 module and your microcontroller for specific connection requirements and guidelines.

Code Examples

### Example 1: Basic Motor Control using Arduino

This example demonstrates how to control two DC motors using the L298 2A Dual Motor Driver Module with PWM control using an Arduino board.

```c
const int enA = 2; // Enable pin for motor A
const int in1 = 3; // Input pin 1 for motor A
const int in2 = 4; // Input pin 2 for motor A
const int enB = 5; // Enable pin for motor B
const int in3 = 6; // Input pin 1 for motor B
const int in4 = 7; // Input pin 2 for motor B

void setup() {
  // Set the enable pins as output
  pinMode(enA, OUTPUT);
  pinMode(enB, OUTPUT);
  
  // Set the input pins as output
  pinMode(in1, OUTPUT);
  pinMode(in2, OUTPUT);
  pinMode(in3, OUTPUT);
  pinMode(in4, OUTPUT);
}

void loop() {
  // Set motor A to move forward at 50% speed
  digitalWrite(enA, HIGH);
  digitalWrite(in1, HIGH);
  digitalWrite(in2, LOW);
  analogWrite(enA, 128); // 50% duty cycle

// Set motor B to move backward at 75% speed
  digitalWrite(enB, HIGH);
  digitalWrite(in3, LOW);
  digitalWrite(in4, HIGH);
  analogWrite(enB, 192); // 75% duty cycle

delay(1000); // Wait for 1 second

// Stop both motors
  digitalWrite(enA, LOW);
  digitalWrite(enB, LOW);
  delay(1000); // Wait for 1 second
}
```

### Example 2: Robotics Application using Python and Raspberry Pi

This example demonstrates how to control two DC motors using the L298 2A Dual Motor Driver Module with PWM control using a Raspberry Pi and Python.

```python
import RPi.GPIO as GPIO
import time

# Set the GPIO mode
GPIO.setmode(GPIO.BCM)

# Define the pins
ena = 17
in1 = 23
in2 = 24
enb = 25
in3 = 12
in4 = 16

# Set the enable pins as output
GPIO.setup(ena, GPIO.OUT)
GPIO.setup(enb, GPIO.OUT)

# Set the input pins as output
GPIO.setup(in1, GPIO.OUT)
GPIO.setup(in2, GPIO.OUT)
GPIO.setup(in3, GPIO.OUT)
GPIO.setup(in4, GPIO.OUT)

while True:
  # Set motor A to move forward at 50% speed
  GPIO.output(ena, GPIO.HIGH)
  GPIO.output(in1, GPIO.HIGH)
  GPIO.output(in2, GPIO.LOW)
  GPIO.PWM(ena, 50) # 50% duty cycle

# Set motor B to move backward at 75% speed
  GPIO.output(enb, GPIO.HIGH)
  GPIO.output(in3, GPIO.LOW)
  GPIO.output(in4, GPIO.HIGH)
  GPIO.PWM(enb, 75) # 75% duty cycle

time.sleep(1) # Wait for 1 second

# Stop both motors
  GPIO.output(ena, GPIO.LOW)
  GPIO.output(enb, GPIO.LOW)
  time.sleep(1) # Wait for 1 second
```

Note: In both examples, the motor speeds can be adjusted by changing the PWM duty cycle values. Additionally, the direction of the motors can be reversed by swapping the input pins (IN1 and IN2 for motor A, and IN3 and IN4 for motor B).
