and now I have a doubt.
Can we connect arduino directly to blynk without any type of connection? Logically I feel we can’t. But in this link they have not mention anything about a WiFi connection or other types of connection so it creates that doubt in me. Can someone give an explanation?

You can also do a connection via USB, but that’s not really a long term solution.
The best option is to scrap the Arduino and choose a board that has built-in Wi-Fi…
I thought I’d write a piece about my thoughts on the best hardware to use for your IoT projects if you’re just starting-out with Blynk.
I did what many people do, started-off buying an Arduino Uno and uploaded some code to make it flash an LED. After about 10 seconds of watching the LED flash I was bored, and wanted to do more (I have a short attention span
The next task was getting the Uno connected to the internet and I chose the Ethernet Shield route. After around 6 months of m…
