Use real PWM output in default settings

[macxsm]

Hi,
according to the very nice image from
http://learn.acrobotic.com/tutorials/post/esp8266-getting-started
the pins you use are not all pwm-capable.
Instead you should use pin 2+5+6 instead of 5+6+7, because 7 is not PWM.

Bye!

There are many flavours of ESP8266 boards, with different pinouts. Mine are definitely PWM-capable, but your board could be very different.

Ah OK.
I was looking at the ESP-12e and the NodeMCU which have both the same pins for PWM.
Even if it works with the ports you selected, I think I noticed some unsmoothness when the color of the not-pwm-pin (as documentation says) appears.
Anyway, not an issue, because it's configurable.
Thanks for sharing!
