I am rather new to this arduino stuff I have programmed a program for my own cabin with a lot of things, but i am working on a backup, to start an inverter in case of a power outage.
I then have a small voltage sensor module, but i can’t understand the program to use.
It says :
What does “VAL11” and “VAL2” means or stand for?
Where should i connect the analog cable to the arduino board? (analogRead(1)) ??
The other prgrams i have done, i have more or less undertood what i copied and pasted into the arduino program, (at least after a while), but this one… Not a all…
Will be very happy if someone can help out…
