I'd be interested to know why you think "the simplest ESP8266" would be easier to use?
Which are the simpler ways on connecting to the Arduino wirelessly to the PC just to be able to control it with an usb contorler from a PC or maybe transfer data.
After playing with Arduino and making a 4 wheel robot on my own now i am struggling with the Wi-Fi extension. I studied adding the esp 8266 but i think there should easier ways to connect to the Arduino wirelessly.
What are you struggling with exactly?
