How to let arduino detect R Y B phases?

I am looking for a way to detect R Y B phases
if the phases connected in wrong order want to display the order on LCD or serial monitor
is there any code to test?

If you are working with 3 phase power, the Arduino should be one of the last things you should consider using.

Have You heard about Oncle Google?
He has this: embedded - 3-phase voltage monitor / Phase sequence using Arduino + EmonLib - Stack Overflow

code to test? Should be fairly easy to make.

Sure, I will not use 3 phases directly to arduino :slight_smile:

where is the part of code that show the order of phases?

Phase relationship only matters in 3 phase motors. Hook it up. If it spins the wrong way, swap any two phases. No gadgets needed. Phase designation is arbitrary.
