Home automation is the present and future for home appliances and devices. A smarter lighting solution is to use wireless light switches and dimmers. Standard dumb light bulbs is the only we are conditioned to control light switches. The more convenient way to control all our home lights is when we turn ON or OFF all lights at once. This automation project using Atmega328p microcontroller is used to controlling AC load with the use of Bluetooth. The intensity of AC loads can be controlled using the provided android app; firstly, the load is selected using the android app, then we can change the intensity of the load up and down while the joystick buttons are pressed. The up button will increase the intensity, while the down button will decrease respectively. We use an atmega328P microcontroller which is interfaced with a Bluetooth module which is connected to the android app. The commands are then sent by the android app is received and further processed by the controlling. So, basically, we can control up to 5 AC Loads individually using this circuit.
