In my app i can see thst my button is toggling when im pressing that should stop the water pump but its not stopping it (I am using arduino uno just for the 5v to power the railway that is connected the vin pin and the vcc for relay)

Post the schematic.

Does the relay coil have a diode across if for inductive spike suppression?

 

Post the schematic.

Does the relay coil have a diode across if for inductive spike suppression?

This is the architecture i went for (but i am taking 5v from another board bcs my vin pin is not getting 5v with cable attached idk why)

 

That's not a schematic, it's a wiring diagram.

How exactly does is the relay coil being driven?
