Thank you for your project. Today I successfuly conntrol my air conditioner by Arduino Uno. But I'd like to use esp8266 to put in my local web. I noticed that in this project, ESP8266 is under the "SOFT Pinout". Could you please explain what the "SOFT Pinout" means? Why there are two pins needed? When I use Uno, Pin3 is enough. Please tell me why. Thank you! Best wish for you.
