I want to do an project on AUTOMATIC HOME LIGHTING SYSTEM.
Project is to work in such a way that If someone enters a room the light should be ON with that if that person want to turn the light off he can also control that using a bluetooth module (HC-05). And this system will only work when there is no sunlight in order to save energy using LDR.
I have tried to write the code upto the bluetooth module. I have attached the code upto the BLuetooth module I have tired but this is not working well.
So Kindly please help me with a working code for this project.
Thank you so much in advance.
