Hi There …
I am an IT … in my city a lot of student can’t using Arduino with Blynk
because when they using esp-01 or any esp small shield (not talking about NodeMCU or ESP32 or any device can work alone … i mean they small chip that have rx and tx connect to arduino…)
when they search on internet also me …we find the “AT Command” only no library
but there are type of project that used esp as main device
we want use esp as bridge between arduino and blynk
i didn’t find this solution from years
student force to go to NodMCU (esp-12e) were most old library for peripheral not work good
and only A0 one along in
i wish see an example to send string from arduino to Blynk and vise versa using esp-1 (small chip only have rx and tx)
