A6 and A7 pins are not working

I’m checking the relay with esp and arduino nano. But the a6 a7 pins do not pull the relay. why

Even with the very limited information you provides, this that is not a Blynk related question… if you need to learn about how to use your ESP and Arduino prior to learning how to use Blynk, then I recommend starting with the the Arduino site: https://www.arduino.cc/en/Guide/HomePage and the espressif site: http://espressif.com

Meanwhile… A6 and A7 are Analog pins, and they are for reading data from appropriate sensors, not activating things like relays… that is the job of Digital pins.



There are also many Documents and Help Guides on the links at the top right of this page.

I know they have analog pins. But other analog pins(A1 A2 A3 A4 A5) work with the relay. These are just not working. Digital pins full

Try a shift register and use digital pins.


@oksijen Well, you are still not providing much detail… Whether Analog pins or Digital pins work or not is not really a Blynk specific issue… places expand upon your information so we can do more than take guesses.

Are you using virtual pin control or direct pin control in the App?

If you are using the Analog pins, have you set them up correctly in setup() to be used as digital?

Show us your sketch so we can see if there is any issues there,

@oksijen - learn how to use a forum.

A6 and A7 are analog only - ie no digital out.
