thanks for offering to help! no, i was uncertain about 7 being a pwm pin, i was using a reference from acrobotics "ESP-12E DEVELOPMENT BOARD PINOUT" this may not be accurate...
using a very simple sketch modified for the board... it's the example sketch that comes with the library, "doesn't work" is not helpful at all... i cannot get the LED to
turn off, i've added my own code to attempt to make the LED go dark, unsuccessfully, another "doesn't work" is getting red hues, but that's trivial for my experiment, i think it's a matter of resistor values....
