Also, if you have a 5V Uno (by which I mean the high-voltage on a pin is 5V), you could damage your esp8266 by connecting the two together. | |

here's how i have wrote the code for Softserial : in Arduino SoftwareSerial ArduinoUno(3,2) // rx | tx in esp8266 SoftwareSerial esp(D2 , D3) //rx | tx While wiring, I have wired 3 -> D3 and 2 -> D2. As far as power supplies go, I have connected them both to PC's usb port . In both codes I have kept Serial.begin(9600) and SoftwareSerial.begin(4800)
