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.
