  Heartbeat LED

  dimms up and down.
  Can be used for a "heartbeat" LED
  
  you must connect the LED to a PWM enabled PIN

// 5 August 2023: Changes to make it work in Wokwi:
//                All files of the library uploaded as local files.
//                No sub-folders.
//                Changed includes to local inclused with "
//                Removed include from bottom of Noiasca_led.h
//
