L298N Lib

Library for controlling L298N Motor Controller based on the Adafruit Motor Shield Library, includes classes and two functions.

Constructor: L298N_Motor

Usage:

L298N_Motor myMotor(uint8_t pinA, uint8_t pinB, uint8_t pinEn);

Example:

L298N_Motor myMotor(2, 3, A0);

Arguments:

• uint8_t pinA: Output pin #1 for the motor.
• uint8_t pinB: Output pin #2 for the motor.
• uint8_t pinEn: Enable pin for the motor (-1 if enable is not used).

Method: run

Usage:

• Using keywords:
  • myMotor.run(FORWARD); //2
  • myMotor.run(RELEASE); //1
  • myMotor.run(BACKWARD); //0
• Using integer values:
  • myMotor.run(0); // BACKWARD
  • myMotor.run(1); // RELEASE
  • myMotor.run(2); // FORWARD

Example:

myMotor.run(FORWARD); // Motor will run {PinA: HIGH, PinB: LOW}

Arguments:

• uint8_t motorState: Controls motor direction with the following values:
  • 0 (or BACKWARD): {PinA: LOW, PinB: HIGH}
  • 1 (or RELEASE): {PinA: LOW, PinB: LOW}
  • 2 (or FORWARD): {PinA: HIGH, PinB: LOW}

Method: setSpeed

Usage:

myMotor.setSpeed(uint8_t speed);

Example:

myMotor.setSpeed(255);

Arguments:

• uint8_t speed: Speed value between 0 and 255 (for PWM control).
