Mount the sensor shield on Arduino Boar and connect the shield to the relay modulde following the statement below.

link:

module ->  Shield

  in1        ->  pin 13

  in2        ->  pin 12

  in3         -> pin 11

  in4         ->  pin 10

  in5         -> pin 9

  in6         -> pin 8

  in7         ->  pin 7

  in8         -> pin 6

 

Take care not to invert the wires.

 The battery is connected as follows: A wire was added to the negative pole connected to GND and the shield and the other of the DC relay module.

  The module was connected to the wire GND which is the same shield plate Arduino.
