Arduino IoT Cloud – Relay Switching

The relays will be operated using the Arduino IoT cloud platform. They can be controlled by using a web application or a mobile application. This project will help you understand how different variables can be associated.    


The hardware requirements are,

  • ESP8266
  • Led
  • Jumper wires
  • Relay module
  • USB cable


ESP8266 microcontroller (NodeMCU 1.0 12-E Module) will be used to communicate with the cloud platform. This has a WiFi module attached to it, making it easier for network configuration. The cloud will help to control the relay by changing its state from on to off and vice versa.
