Since commit 2440c240ced0862bbe4472581dd4c08006bc8512 this example doesn't work anymore for ESP32:
//! Turns on LED with the option to change LED intensity depending on `duty`
//! value. Possible values (`u32`) are in range 0..100.
//!
//! This assumes that a LED is connected to the pin assigned to `led`. (GPIO5)
