Grid control using password base authentication system with automation using ardino

These days, societies became very advance, all want security so in this project we show, how to control power distribution  #GSS(gride substation )  and PSS(power substation) using password base

 In this project, we showed how to control GSS and PSS by password:- 

FIRST STAPE:-

IN the take PCB BORD -(printed-circuit-board) show in a figure below:-

TAKE 

5 Pin Mini SPDT Relay 

NUMBER OF relays =3

then a connected relay to relays driver shown in figure

the photo is shown in figure

                                                        RELAY

                           RELAY DRIVE

 The connection of relay and relay drive:-

   shown in figures:-
   

                                     if know how to the connection of relay visit:- https://goo.gl/cuwsmx                                                             

 Then taking, shown in figure:-                                                                                                                                                                                                                         

The connection of display shown in figure:_

IN THIS DISPLAY CHOSE 6 STARTING AND 6 LAST CONNECTION;-
