ESP32 PWM options for a new user

[djsb]

I've started by using standard analogWrite on an ESP32 DevKitC V4, and I'd like to know what my options are when using PWM for LED and motor control. I've tried one example that uses LEDC to fade up/down a single LED, and I have another example that drives an RGB LED. I've read a little about the ESP32 having multiple channels, but I'm a bit confused as to what this means in detail. Also, what options open up for the use of simple DC (3v to 6v) motors and simple 4 wire stepper motors? Is there a separate motor control section, and is it worth using at all for simple motor applications? Is the LED section sufficient for this? Thanks.
