it's not possible for us to completely redo the project, so if you can be a little specific about the problems you are getting, that would be very useful.


when I went through the project I saw there is a clean circuit diagram in the Circuit Description Section.


After that, in the How to Connect Energy Meter with Arduino: Section, there are two images. one showing the connection, to the submeter itself another showing the connection to the optocoupler,


the two purple wires coming from two LEDs go to the optocoupler. for convenience, the wire is connected with the TWO LEDs. as the LEDs in the board have a common terminal.
