bridge1.digitalWrite(9, LOW); // Digital Pin 9 on the second board will be set LOW

I don’t believe you can do this.

You should use virtual pins in the Blynk app, it makes life much easier.

Using Virtual Pins to control physical devices

I thought I’d write a guide about how to use virtual pins with app widgets such as buttons, to control physical devices such as relays, LEDs etc… Why use virtual pins anyway? I’d always recommend using virtual pins over physical pins when developing your code. There are a number of reasons, but here are what I consider to be the main ones: Virtual pins are hardware independent. This means that it’s far easier to port your code from one hardware platform to another in future (when you realise…

Also, it’s impossible to make useful comments on Bridge code based on a small snippet from one device.
You need to post the full sketch from both the sending device and the receiving device.
