L298N Motor Driver Module

The L298N Motor Driver Module is a popular dual H-Bridge driver used for controlling DC motors and stepper motors. It allows you to drive two DC motors simultaneously, control their speed, and reverse their direction.

Key Features:

• Dual H-Bridge Motor Driver: Controls two DC motors or one stepper motor.
• Voltage Range: Typically 5V to 35V for motor supply, and 5V for logic circuits.
• Current Capacity: Up to 2A per channel (with proper cooling).
• Speed Control: Uses Pulse Width Modulation (PWM) for speed regulation.
• Direction Control: Allows forward, reverse, and brake operations.

Pin Configuration:

• Input Pins (IN1, IN2, IN3, IN4): Control the direction of the motors.
• Enable Pins (ENA, ENB): Enable or disable the motors (used for PWM speed control).
• Output Pins (OUT1, OUT2, OUT3, OUT4): Connected to the motors.
• Power Pins: VCC (for logic) and 5V-35V (for motor power supply).

Basic Connections:

1. Power Supply: Connect the motor power supply (e.g., 12V) to the +12V pin and ground to GND.
2. Motor Connections: Attach motors to OUT1, OUT2 (for motor A) and OUT3, OUT4 (for motor B).
3. Control Pins: Connect IN1, IN2, IN3, IN4 to a microcontroller (like Arduino) to control motor direction.
4. PWM Control: Use ENA and ENB pins for speed control with PWM signals.

Arduino Example:

int motorA1 = 3; // IN1
int motorA2 = 4; // IN2
int enableA = 5; // ENA (PWM)

void setup() {
  pinMode(motorA1, OUTPUT);
  pinMode(motorA2, OUTPUT);
  pinMode(enableA, OUTPUT);
}

void loop() {
  digitalWrite(motorA1, HIGH);
  digitalWrite(motorA2, LOW);
  analogWrite(enableA, 128); // 50% speed
  delay(2000);
  
  digitalWrite(motorA1, LOW);
  digitalWrite(motorA2, HIGH);
  analogWrite(enableA, 128);
  delay(2000);
}
