Blynk + Relay + arduino Uno

Hey guys! This probably gonna sound really dumb of me but I'm new to this.

So, I setup a relay + lighbulb to my arduino and connecting it via bluetooth HC-06. Everything is fine.

I created a project in Blynk, in the output section, I put digital 13 as my connection(same like in arduino board).

I used Blynk Bluetooth Examples to connect Blynk with the boards and I did not add any codes in it.

When I run the project, the bulb suppose to light up when I press switch button ON and turn off when i press OFF.

But mine did the opposite. When I press OFF it switch ON, and when I press ON it switch OFF. Do I have to declare the initials state in arduino code?

I know that you just can change the value in OFF = 1 and ON = 0 for it to make it work.

But my OCD side wouldn't let me.

Please be nice and Thank You!

Some relays are connected at LOW and disconnected at HIGH. Some relays have NC and NO pins. Perhaps you wired the NC pin.
