This project is all about serial communication between ESP8266-12(NODE-MCU) and Arduino. As we know ESP-12 have one analog pin where we can connect our analog sensor, But what else if we need more than one analog pin to connect more analog sensor and again if you want to send data to server like adafruit.io or your own server. Jan 01, 2015 Following on from the FTDI + ESP8266 post, if you do not have a FTDI serial adaptor you can use an Arduino. Here is how to set up the Arduino to talk to the ESP8266. I an using a 5V Arduino Nano which of course is 5V. The Esp8266 is a 3.3v device and so I am using a voltage divider to bring the Arduinos 5V down to 3.3v. I am trying to achieve communication between two ESP8266, ie one acts as a server and the other acts as a client, where i am passing the string from the server's serial monitor to the client. This Serial can be used to transmit data in USART mode to another Serial Device as well as see any Debug data in the Serial terminal. However, both the functionality can not be used simultaneously. The Tx Rx pair of Arduino can be connected to one pair of other device i.e. Either to the computer via the cable or to the Tx Rx of ESP8266.

Esp8266 Serial Communication To Arduino Free
Im trying to send Data from the ESP8266 to the Arduino but if i send anything the Arduino only receives a 10 if I connect my ESP to my PC i get the correct Numbers i sent. This is the Code that is on the ESP for testing the Serial Communication.
Serial Communication between ESP2866-12 (NODE-MCU) and Arduino to increase the number of analog pins as my primary work.
