thats the library im using for the usb to wifi or bluetooth dongle
Sorry, but this is not really something we can help with here… this is the Blynk forum, so once you figure out what you need (Arduino forum perhaps?), then we can assist with your learning/using Blynk over that link.
Or like most other regular users here will probably say… get an ESP8266 or ESP32 Dev board for a few bucks and start using Blynk right away
it would be better to buy a nodemcu for only $ 3, or an esp32 for $ 5
how would it be better if i already have a usb dongle, lol if u want to buy me one go ahead i can put my mailing address
It would only be better if you haven’t yet figured out how to get your Arduino/USB WiFi dongle online… If you have figured out how, then obviously what you have is better $$ wise than what you have to buy.
