Hi, I really having a hard time to connect blynk virtual pin to nodemcu pin. I try to read it on blynk docs but can’t get it. The problem is what pin should I choose on nodemcu pin. Can somebody give me an example how to make it in LED, PIR, and Fingerprint… The other thing is can I make it on wifi mode not the ethernet?Thanks guys…
Virtual Pin has no physical representation. It’s a storage or a “channel” to send variables from the app to hardware and back.
You can choose any connection method you like: wifi, ethernet, usb, 3g…
