//  Authors: Dan G Ogorchock
//
//  Summary:  EX_PWM_Dim is a class which implements the SmartThings "Switch" and "Switch Level" device capabilities.
//			  It inherits from the st::Executor class.
//
//			  Create an instance of this class in your sketch's global variable section
//			  For Example:  st::EX_PWM_Dim executor1(F("dimmerSwitch1"), PIN_SWITCH, PIN_LEVEL, LOW, true);
//
//			  st::EX_PWM_Dim() constructor requires the following arguments
//				- String &name - REQUIRED - the name of the object - must match the Groovy ST_Anything DeviceType tile name
//				- byte pin - REQUIRED - the Arduino Pin to be used as a digital output
//				- byte pin_pwm - REQUIRED - the Arduino Pin to be used as a pwm output
//				- bool startingState - OPTIONAL - the value desired for the initial state of the switch.  LOW = "off", HIGH = "on"
//				- bool invertLogic - OPTIONAL - determines whether the Arduino Digital Output should use inverted logic
//
//  Change History:

//    ----        ---            ----
//    2016-04-30  Dan Ogorchock  Original Creation
//    2018-08-14  Dan Ogorchock  Modified to avoid compiler errors on ESP32 since it currently does not support "analogWrite()"
//    2018-08-30  Dan Ogorchock  Modified comment section above to comply with new Parent/Child Device Handler requirements
//    2018-08-30  Dan Ogorchock  Adding reporting of 'level'
//    2018-12-06  Dan Ogorchock  Fixed Comments
//    2019-04-10  Dan Ogorchock  Corrected analogWrite() call for ESP8266 platform
//    2019-12-19  Doug Johnson   Created new file based on EX_Switch_Dim to remove separate switch, and add dedicated smoothing
//    2020-04-01  Dan Ogorchock  Added compatability for traditional Arduino Boards
