WORKING AND OUTPUT

Welcome to the Node MCU Based project.

In this project, we use the RemoteXY app to access the Wifi SSID point created by Node MCU after connecting the smartphone to Node MCU’s wifi named as RemoteXY and password as 12345678.

In the app, the ON/OFF switch controls the motion of the fan directly.
