I’m trying to develop a lighting control system.
by the app should open a menu for modes:
Automatic: controls the lamp intensity by the BH1750 sensor, as darkness increases the intensity increases, and shows the lux variation data on the screen
Manual: I can control the intensity of the lamp through the Slider.
I’m using arduino uno, sensor BH1750, and ESP8266
