Hi, i am working on a project where i am using 4 Relays. once i Set any one of the relay the voltage and current should flow to a particular Relay and it should turned on and off. But in my case all the four relays will set and reset . if i turned on or off any particular relay . But i am not getting what could be the reason and what i need to add in my code to work for particular relay to turn on and off. can anyone please help me with this.

Thank you

Actually for controller 3.3V is going . The circuit has been done in such a way that so that the controller gets 3.3V . No need to worry about it. But please help me solve about the relay concept please.
Thank you
