igot error for the project " IoT Based Electricity Energy Meter using ESP12 and Arduino" i am doing this project but i got the program executed for node mcu but i get the error 'acs712_30A was not declared in this scope' for the arduino part . please help me where i went wrong.
HI
The problems with the header file. if you have included the library with the Add .ZIP Library.. method, then you have to do #include <ACS712.h> not #include "ACS712.h".
If you do #include "ACS712.h" the preprocessor is searching the library in the project directory, not in the predetermined directory.
I was add acs712 library and
I was add acs712 library and I also use header#include
Please help

PermalinkHi, it seems the ACS712 sensor library was not installed correctly, so pls check that and if still problem persists, then paste the complete error you are getting.
