Arduino Wifi Rev 2 - incompatibility between Tone and Servo

[dcuartielles]

It is not possible to add a call to tone and, at the same time, invoke the servo. Seems like they are using the same timer. Simply try the following example to replicate the issue:

#include <Servo.h>

void setup() {
  // put your setup code here, to run once:
  pinMode(10, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  tone(10, 900);
}

This will produce the result:

Tone.cpp.o (symbol from plugin): In function `tone(unsigned char, unsigned int, unsigned long)':
Se encontraron varias bibliotecas para "Servo.h"

One possible solution would be changing the megaaver/ServoTimers.h to be using a different timer, e.g.

//#define USE_TIMERB1        // interferes with PWM on pin 3
#define USE_TIMERB2        // interferes with PWM on pin 11
//#define USE_TIMERB0        // interferes with PWM on pin 6

But I am not sure whether this would provoke an issue somewhere else.

Note: this is needed for the EduIntro library to work
