Serial Communication between ESP2866-12 (NODE-MCU) and Arduino to increase the number of analog pins as my primary work.

Serial communication on pins TX/RX uses TTL logic levels 3.3V. Don’t connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your ESP8266 board. Serial is used for communication between the Arduino board and a computer or other devices. Nov 29, 2016  That’s right! USB, which stands for Universal Serial Bus, is a serial port! On the Arduino Uno, this USB connection is broken out through onboard hardware into two digital pins, GPIO 0 and GPIO 1, which can be used in projects that involve serial communication with. Serial Communication between ESP8266 and Arduino Uno. Ask Question Asked 2 years, 2 months ago. Active 11 months ago. Viewed 18k times 1. I want to send data from arduino to ESP8266. I have done all the RX and TX connections. The problem is that data is not sent every second, it stops after a single byte. Serial communication esp8266.

About this project

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.

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. 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. Speedstream 4100 manual.
