Avoid duplicate GPIO assignments!<br>
GPIO 0 and 2 have fixed 10k pullup and must remain high during boot (otherwise flash mode is entered).<br>
GPIO 2 is also connected to builtin LED (active LOW) on most ESP boards, so don't care or strip it.<br>
GPIO 15 has 10k pull-down, so could only be used as active-high in/output.<br>
Some GPIOs go high for some time at boot, so using only active-low logic is advisable, particularly for switching outputs<br>
Invert = active HIGH, default LOW<br>
Impulses are 0 by default (on until off), otherwise will auto-turn-off after specified time in factors of 100ms.<br>
