This library is based on Paul Stoffregen's TimerOne library that provide ability to add more than one callback, which I called "task"

To use this library, you'll need to install Paul Stoffregen's TimerOne as well:

https://github.com/PaulStoffregen/TimerOne

msTask fooTask(1000, Foo);
msTask barTask(5000, Bar);

• The first parameter is task's period

• The second is the callback function:

void Foo(){
	//your Foo task's code here
}

void Bar(){
	//your Bar task's code here
}

This function must be call in setup() once

msTask::init();

fooTask.stop();

fooTask.start();

fooTask.setPeriod(500);

fooTask.setCallback(Bar);

You can read example Blink+AnalogRead, FlashLED or TrafficLight to know how to use.
