We will transfer DHT22 Sensor data from Arduino to NodeMCU and NodeMCU to Arduino. In this tutorial we will learn how to make serial communication between Arduino to ESP8266 & ESP8266 to Arduino.

Feb 15, 2022 · I have included a detailed specification pin diagram of NodeMCU ESP8266 and Arduino UNO. After this article, you will learn how to use Arduino UNO and ESP8266 board with Arduino IDE and the technical difference between the two boards.

Sep 4, 2018 · A tutorial by Arduino User Group Gujarat for getting started with the NodeMCU (ESP8266) on Arduino IDE.

Apr 13, 2018 · We have already seen how to connect Arduino UNO with NodeMCU/ESP8266 over UART and send data to MQTT broker here. That project uses lua to program the NodeMCU devices, to make it simple to use I will use Arduino IDE to program both the devices in this post.

Jan 13, 2022 · My suggestion would be to remove the Uno and program the esp directly with the Arduino code. Because you need 3 analog inputs for your sensors, get an ads1115 module, or maybe a 74hc4051. You need to think about power for those gas sensors.

In the below Instructable we will learn how to install Arduino IDE for ESP8266 so by the end of this Instructable we can run arduino code on ESP8266. Install Arduino IDE software from the link http://www.arduino.cc/en/main/software. After installing Arduino IDE icon is created on the Desktop as show in the figure.

Let’s program Arduino UNO to configure the ESP8266 wifi module as TCP Client and Receive/Send data from/to the Server using WIFI. Here, we are using the Thingspeak server for TCP Client demo purposes.

Jul 22, 2022 · In this tutorial, we will learn to use the I2C Communication between ESP8266-NodeMCU and Arduino Boards. Different Arduino supports at least one I2C port. Similarly, Arduino Uno also has one I2C port (SCL and SDA). We will learn to configure NodeMCU as an I2C master and Arduino as I2C slave device.

Copy the below arduino code and paste into your Arduino IDE and upload the program to your nodemcu or any other esp devices that you are using, make sure to choose the correct port and device name from the board. also don't forget to change the SSID and password to …

Sep 13, 2016 · In this blog we will see how to connect arduino to nodemcu and post data to a mqtt broker. Arduino will take temperature readings and send the readings to nodemcu over serial connection. Nodemcu will send a mqtt message for every reading it receives.
