IoT-Based Smart Bedroom Using NodeMCU-32S

When we come back home after a long day, the bedroom is the best place to rest our minds, and sometimes it is a hassle to turn on all the switches of fans and lamps. Or maybe sometimes we want to open all the fans and lamps earlier even before entering the bedroom. But how to make that possible?

With IoT, everything is possible. In this project, we will control a fan and three lamps in the bedroom from the V-One Dashboard that can be accessed from a web browser on a smartphone, tablet, or computer.
