hi friend…
wiring arduino mega with ESP8266 wifi module it same like old blynk?
and coding to get online also same or just litter bit difference?.
i check example code totally difference.
here my coding and it work fine with old blynk. which part need to adjust for getting online with new blynk 2.0?
