In this project we will show the Arduino Uno board can be connected to Node MCU. This helps to extend wireless capability to Arduino Uno. We are reading values from Gas Sensor and feeding them to Arduino Uno which further sends data to Node MCU. Node MCU using the MQTT protocol sends data to Things Board.
The above block diagram shows the connectivity between the various modules in this project. The various interfaces are:
The code has been uploaded to our GitHub which is available for all who has our YouTube channel Way2Know memberships.
The below video describes the connectivity and explains the connectivity.
