We are going to make an IoT-based cellular device for home automation, which will help you in controlling your home appliances, no matter where you are. Since LDR resistance changes as per ambient light, voltage of NE555 also varies accordingly. This variation in voltage, changes the duty cycle of the output waveform, giving higher duty cycle when ambient light is not present. In this way it can be used to dim the LCD backlight for power saving.
