I'm trying to create a code that will eventually be able to send several different commands to carry out a certain procedure on the NodeMCU.
I've adapted a code I found online to suit this need but I'm having problems with the new settings I've added.
The two new settings equal and set 1 change in unison and not independently as I require e.g. I activate set 1 on the webpage and equal also changes and vice versa. As well as this everytime the page refreshes it resets the variable.
Any advice my code is below I'm probably missing something basic.
set 1 and equal do not need to activate anything at this time but I am trying to code it so that if equal is pressed set 1 goes false. It works like this with the two leds but not with my variables.
code below:
