Control Light Bulb and Relay using Blynk Mobile App

Let's explore how to control light bulb and relay using Blynk mobile app or dashboard. We’ll learn the basics of the single-channel relay. Also, we’ll interface the relay module and light bulb with ESP8266 NodeMCU. This IoT project demonstrates, how microcontrollers control AC-operated devices like a light bulb, fan, etc. through the relay. In the end, you’ll be able to control the light bulb through the Blynk IoT Platform. This video is a part of Blynk video tutorial series.
