Assembling demo piece to show " 100% vvpat is useless ", we need to connect relay ( spark rail ) and battery bulb first and test it.

First while connecting relay using mobile USB i confused their are four different tiny wires inside USB cable, which wire to choose?

And we have to findout on one side of relay mentioning as "+5v supply", below this their are two points one is "GND" another is "+5v", exactly otherside of this 2 points their are two terminals for connecting USB wires.

Now, out of 4 wires from USB cable select:-
RED coloured wire, connect to +5v terminal
BLACK coloured wire, connect to GND terminal
Once done and plug-in the USB we notice red light in relay.

On opposite side of USB connected terminal we can see, out put terminals for connecting to battery bulb ( i took help from team shared video to do this connection)

Then, I connected Apk app and printer via Bluetooth. Later while testing in apk app, "bulb is not connecting" while "printer is connecting", Because, I didn't know that relay must also connect via Bluetooth.

We need to connect both printer and relay via Bluetooth. While connecting relay Bluetooth itself displays password enter " 0000 " or " 1234 " any one it takes to connect.

Tested entire connection working fine exactly as in video. Now im assembling the entire setup inside the box.
