Typo?
Not a good idea to mention the “C” word here

If you want to add more relays then you simply need to add another pinMode declaration in void setup and additional BLYNK_WRUTE(vPin) handlers for your other datastreams.

If you want to control multiple relays from one virtual pin, or learn more about virtual pins in general, the read this…

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…
