<p>Chronometer/stopwatch library that counts the time passed since started.</p>

<h2>Get It!</h2>
<li><a href=""><strong>Download the source</strong></a></li>
<li><a href="">Chrono on Github </a></li>
<h2>Adding Chrono</h2>
<p>Copy the <span class="hilite">Chrono</span> folder to your Arduino or Wiring <span class="hilite">libraries</span> folder.
<h2>Basic Example</h2>
<pre class="prettyprint" ><code>
// Documentation :
// Download :
#include &lt;Chrono.h&gt;
// Instanciate a Chrono object.
Chrono myChrono;
void setup() {
// Start the chronometer on setup.
void loop() {
// Check whether the chronometer has reached 1000 time units.
if (myChrono.hasPassed(1000)) {
// Do something here...
// Restart the chronometer.
<h2>Basic Usage</h2>
<h3> Include the library </h3>
<pre class="prettyprint" ><code>// INCLUDE CHRONO LIBRARY :
#include &lt;Chrono.h&gt;
<h3> Create an instance </h3>
Once a Chrono is created, it starts counting (in milliseconds by default).
<pre class="prettyprint" ><code>
Chrono myChrono;
<h3> Basic Methods </h3>
<td class="first">elapsed()</td>
<td class="second"><span class="type number">unsigned long</span></td>
<td> Returns the elapsed time</td>
<td class="first">restart()</td>
<td class="second"><span class="type void">void</span></td>
<td>Starts/restarts the chronometer</td>
<td class="first">hasPassed( timeout )</td>
<td class="second"><span class="type boolean">bool</span></td>
<td>Returns true if the chronometer passed the timeout</td>
<h2>Advanced Usage</h2>
<h3> Time units </h3>
You can create a Chrono that counts in microseconds or seconds:
<pre class="prettyprint" ><code>Chrono myChronoMicros(Chrono::MICROS);
<pre class="prettyprint" ><code>Chrono myChronoSeconds(Chrono::SECONDS);
<h3> Custom time function </h3>
Alternatively you can create a Chrono with a custom time function:
<pre class="prettyprint" ><code>unsigned long mySpecialTimeFunction();
Chrono myChronoMicros(mySpecialTimeFunction);
<h3>Advanced Methods</h3>
<td class="first">restart( offset )</td>
<td class="second"><span class="type void">void</span></td>
<td>You can alternatively start(restart) the chronometer with a time offset</td>
<td class="first">stop()</td>
<td class="second"><span class="type void">void</span></td>
<td>Stops/pauses the chronometer</td>
<td class="first">resume( )</td>
<td class="second"><span class="type void">void</span></td>
<td>Resumes the chronometer</td>
<td class="first">hasPassed( timeout,restartIfPassed )</td>
<td class="second"><span class="type boolean">bool</span></td>
<td>If the chronometer passed the timeout, returns true and restarts the chronometer </td>
<td class="first">add( time )</td>
<td class="second"><span class="type void">void</span></td>
<td>Immediately adds some time to the chronometer</td>
<td class="first">isRunning( )</td>
<td class="second"><span class="type boolean">bool</span></td>
<td>Returns true if the chronometer is currently running</td>
<td class="first">delay( time )</td>
<td class="second"><span class="type void">void</span></td>
<td>Waits for some time (in the time unit of the chronometer)</td>
