+Creating an instance of this **class** initializes an ESP-NOW connection from the current device to a device with the specified *macAddress*. Arguments, along with their defaults if left unspecified, are as follows:
 
-  * *pin* - the pin on which the PWM control signal will be output
+  * *macAddress* - the MAC Address of the device to which you are connecting, in the form "XX:XX:XX:XX:XX:XX" the pin on which the PWM control signal will be output
   * *level* - sets the initial %duty-cycle of the PWM from from 0 (LED completely off) to 100 (LED fully on).  Default=0 (LED initially off)
   * *frequency* - sets the PWM frequency, in Hz, from 1-65535 (ESP32 only) or 5-65535 (ESP32-S2 and ESP32-C3).  Defaults to 5000 Hz if unspecified, or if set to 0
