Our proposed system allows user to automate his/her home appliances through simple mouse clicks. We bring the entire home automation functionality on users PC. User may operate all lights fans easily while working on his/her PC bys simply clicking on a user friendly computer application. Here we use serial communication to communicate between the PC and microcontroller based circuit. The microcontroller is used to receive and decode load switching commands sent theough PC serially and then operate loads accordingly. Our system also allows user to get status of loads current status. In this case the pc sends a status request to the microcontroller circuit and the microcontroller then retrieves the load status and sends this data serially to the PC. The PC appilcation now receives the data and displays the results to the user. Thus this system demonstrates the use of microcontroller
based PC home automation system.
Note: This project only works on Computers having Serial communication port, which is usually present in desktop computers not on laptops
