Create a Motor Class

[theDataSmith]

This class will represent a single motor. It will send data over three pins to the motor driver. It should have a constructor that takes the numbers (int) of the three pins as arguments and stores them. Those three pins are:

• Forward
• Backward
• PWM

The motor has four modes, depending on which of the forward and backward pins are high/low:

Forward	Backward	Mode
LOW	LOW	Coast
HIGH	LOW	Forward
LOW	HIGH	Backward
HIGH	HIGH	Brake

The PWM pin controls how fast the motor turns when it's in the forward or backward mode.

Needed Arduino functions:
pinMode()
digitalWrite() (for the forward and backward pins)
analogWrite() (for the PWM pin)

The class should have the following public functions

• void setSpeed(float speed)
  • Takes a value between -1 and 1, and sets the direction and speed of the motor. -1 for backward, 1 for forward.
• void coast()
  • Sets the speed to 0 in coast mode.
• void brake()
  • Sets the speed to 0 in brake mode.
