ESP8266 with ESP-01 adapter - Switching LED Control on/off WiFi Smartphone Arduino Basic Setting
2 days of work to improve this Arduino code.
So far, I've spent 10 days on this project, just to turn a LED on/off
(now using my smartphone).
Anyway, no update of the firmware (and related flasher - FT232RL for the ESP8266) is required.
You don't have even to install the NodeMcu, this is pure Arduino code... and it works!!!
