Hello, I have Arduino R3 with Built-In Wifi ESP8266...
I have error when I try to serial communication between uno + esp8266 + blynk...
When the switch 1 and 2 are on, the esp8266 can't connect to blynk...
Any help?
Thank you
Can we have your code and photos of the wiring?
Thanks.
That will help us help you.
the code is just simple, and no wiring.... it's built in arduino r3 wifi
Can we have the code please?
Can the esp be programmed?
Or just the Atmega328?
nevermind, I've solved it...
with flash the esp8266 to AT Command firmware
and a little bit coding at the uno
