This is my C# implementation. It uses a string as the direction facing to make it a little easier to debug.

public string facing = "right";
public string previousFacing;

private void Awake()
{
    previousFacing = facing;
}

void Update()
{
    // store movement from horizontal axis of controller
    Vector2 move = Vector2.zero;
    move.x = Input.GetAxis("Horizontal");
    // call function
    DetermineFacing(move);
}
// determine direction of character
void DetermineFacing(Vector2 move)
{
    if (move.x < -0.01f)
    {
        facing = "left";
    }
    else if (move.x > 0.01f)
    {
        facing = "right";
    }
    // if there is a change in direction
    if (previousFacing != facing)
    {
        // update direction
        previousFacing = facing;
        // change transform
        gameObject.transform.Rotate(0, 180, 0);
    }
}
