Description

Wifi controlled light

Abstract
      In this project, we can control the lights in our home using NodeMCU and Blynk app. When we send the serial commands from Blynk app we can either ON or OFF the lights using relays. In this project, we are using NodeMCU ESP8266 which is a low cost open source IoT platform.  By connecting to the Wifi network , we can control the lights using Blynk app from anywhere in the world.

Proposed system

• In this project, we are sending the serial commands to NodeMCU by using Blynk app.
• By connecting to the wifi network , we can ON/OFF the lights which is connected with the relay modules.

• NodeMCU ESP8266
