In this article, we have build smart curtains using ESP32 and LDR sensors. This would be used to draw the curtains or window panels and you can control your room lighting according to need.

Arduino is used for controlling the light at the transmitter side. At the receiver, the photodiode or Light-Dependent Resistor (LDR) changes over the received data into original information. A working ...

This paper focus on the idea of automatic lightning system and peculiar way of implementation with embedded tool systems. The proposed method is used to measure and control the intensity of light in ...
