 This code example uses the default period of 0.020s and ramps the duty cycle from 0% to 100% in increments of 10%.

 ## PwmOut code examples
 
 ### Example one
 
 This code example sets the period in seconds and the duty cycle as a percentage of the period in floating point (range: 0 to 1). The effect of this code snippet will be to blink LED2 over a four-second cycle, 50% on, for a pattern of two seconds on, two seconds off.

 ### Example two
 
 The following example does the same thing, but instead of specifying the duty cycle as a relative percentage of the period, it specifies it as an absolute value in seconds. In this case we have a four-second period and a two-second duty cycle, meaning the LED will be on for two seconds and off for two seconds.
