Multiple header files

Projects Programming
1

I am trying to create a few classes to use in my project. The problem is I get an error whenever I try to include multiple header files saying that the second class I import is not a valid type. Each of my classes work fine if I import only one.

Any help would be greatly appreciated.

main.ino

#include "ranger.h"
#include "speedControl.h"


ranger myRanger(7,8);
speedControl mySC(1);
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  Serial.print("   Range:   ");
  Serial.print(myRanger.medianPingCM(5));
  Serial.print(" cm ");
  Serial.print(myRanger.pingCM());
  Serial.println(" cm");
  
  delay(10);
}

ranger.h

#ifndef ranger_h
#define ranger_h
#include "Arduino.h"



class ranger{
  public:
    ranger(int pingPin, int inputPin);  // the constructor for the class.  attaches the ranger object to a pin number
    long ping();
    long pingCM();
    long pingIN();
    void setPin(int pingPin, int inputPin);
    long medianPing(int totalPings);
    long medianPingCM(int totalPings);
    long medianPingIN(int totalPings);
  private:
    int _pingPin, _inputPin;
    long microsecondsToCentimeters(long microseconds);
    long microsecondsToInches(long microseconds);
};

...

speedControl.h

#ifndef speedControl_h
#define speedControl_h


#include <Servo.h>
#include "Arduino.h"
// end boiler plate

class speedControl{
  public:

Post complete files and complete error message.

In the second header you have #include <Servo.h>
You need this in main.ino as well.
