Countimer

This is simple timer and counter Arduino library.
Offers three work modes:

• Count-up timer with call specified method when count is complete.
• Count-down timer with call specified method when count is complete.
• Calling any method at a specified time interval.

It allows you to start/pause, stop or restart timer.
The following are public methods for actions:

• void start()
• void stop()
• void pause()
• void restart()

Other methods:

• byte getCurrentHours()
• byte getCurrentMinutes()
• byte getCurrentSeconds()
• void setInterval()
• String getCurrentTime()
• bool isCounterCompleted()
• bool isCounterRunning()
• bool isStopped()

And here's some sample code!

#include "Countimer.h"

Countimer timer;

void setup() {
	Serial.begin(9600);

    // Set up count down timer with 10s and call method onComplete() when timer is complete.
    // 00h:00m:10s
	timer.setCounter(0, 0, 10, timer.COUNT_DOWN, onComplete);

    // Print current time every 1s on serial port by calling method refreshClock().
    timer.setInterval(refreshClock, 1000);
}

void refreshClock() {
	Serial.print("Current count time is: ");
    Serial.println(timer.getCurrentTime());
}

void onComplete() {
	Serial.println("Complete!!!");
}

void loop() {
	// Run timer
	timer.run();

    // Now timer is running and listening for actions.
    // If you want to start the timer, you have to call start() method.
    if(!timer.isCounterCompleted()) {
      timer.start();
    }
}
