<h3>FRM_PWM</h3>
<ul>
represents a pin of an <a href="http://www.arduino.cc">Arduino</a> running <a href="http://www.firmata.org">Firmata</a>
configured for analog output.<br>
The value set will be output by the specified pin as a pulse-width-modulated signal.<br>
Requires a defined <a href="#FRM">FRM</a>-device to work.<br><br>
This module represents a pin of a <a href="http://www.firmata.org">Firmata device</a>
that should be configured as a pulse width modulated output (PWM).<br><br>
Requires a defined <a href="#FRM">FRM</a> device to work. The pin must be listed in the internal reading "<a href="#FRMinternals">pwm_pins</a>"<br>
of the FRM device (after connecting to the Firmata device) to be used as PWM output.<br><br>

toggles the pulse-width in between to the last value set by 'value' or 'dim' and 0 respectivly 100%<br>
</ul>

<li>
<code>set &lt;name&gt; value &lt;value&gt;</code><br>

</ul>
<ul>
The min value is zero and the max value depends on the Firmata device (see internal reading<br>
"<a href="#FRMinternals">pwm_resolutions</a>" of the FRM device). For 8 bits resolution the range
is 0 to 255 (also see <a href="http://arduino.cc/en/Reference/AnalogWrite">analogWrite()</a> for details)<br>

<li>attribute <i>stateFormat</i><br>
In most cases it is a good idea to assign "value" to the attribute <i>stateFormat</i>. This will show the
current value of the pin in the web interface.
