DCMotorController

This arduino library is meant to simplify the use of DC motor drivers. It supports motor drivers that both:

1. Take a single PWM speed input for speed (e.g., Spark Max)
2. Take three wires: one PWM input for speed, and two digital inputs for direction (forward and reverse). This supports the L298N driver or similar.

Usage

First, initialize the motor controller with the appropriate pins. If you're using a driver that takes three wires, use the following constructor:

//                       (PWM-capable pin, Forward pin, Reverse pin)
DCMotorController dcMotor(3,                7,          8);
dcMotor.begin(); 

Otherwise, if you're using a driver that uses only a single PWM input, input only that pin to the constructor:

//                      (PWM-capable pin)
DCMotorController dcMotor(3);
dcMotor.begin(); 

Finally, the motor driver can be used with the setSpeed function. The speed parameter is a float between -1 and 1, where -1 is full reverse and 1 is full forward (0 is stop).

dcMotor.setSpeed(0.5);
