Can't get any pin control on ESP-12F
Posted: Thu Jun 25, 2020 1:01 amHi all! I'm trying to get one, any, of the pins on this module to go high. The module looks like this;
And is allegedly an ESP-12F, but its pinout seems slightly different to what I've been able to look up (there's a 5V out that isn't in most of the images).
My code, using Arduino IDE, looks like this;
The last few lines are to try and diagnose, but when I try to detect a pin going up and down every second, I can't. What am I doing wrong? The rest of the code works fine...
