// Example 6 changes Example 5 so that LED #2 is now dimmable, instead of just on/off. This requires us to create a new
|
||
|
|
// derived Service we will name "DEV_DimmableLED" Instead of creating a new file to store this definition, we will simply
|
||
|
|
// tack it on to the end of the DEV_LED.h file that includes the code we created in Example 5 to control an on/off LED.
|
||
|
|
// Grouping similar-style Services in one ".h" file makes it easier to organize your custom devices.
|
||
|
|

// As usual, all previous comments have been deleted and only new changes from the previous example are shown.

|
// NOTE: The Arduino/ESP32 code base does not include the function analogWrite() which is typically used to create a PWM
|
||
|
|
// output to drive the brightness of an LED. The ESP32 code base itself includes a set of functions to create PWM output
|
||
|
|
// and the ESP32 chip has built-in PWM functionality specifically for this purpose. There are numerous libraries
|
||
|
|
// you can download that mimics or reproduces analogWrite() in some form or another. HomeSpan conveniently comes with
|
||
|
|
// its own version of a wrapper around the ESP32 PWM classes that make it very easy to define LED pins, and set the
|
||
|
|
// PWM level (or duty cycle) from 0-100%. These functions are encapsualted in the LedPin class, as defined in
|
||
|
|
// extras/PwmPin.h. We will include this file in our updated DEV_LED.h for use with DEV_DimmableLED.
