I am very god at micro-processors and micro-controllers.
I have done quite a few projects on it.
Our project was automatic temperature control of a room depending upon number of people , this helps to ensure an ideal room temperature and there is an added advantage by knowing the number of people in the room because during any emergency evacuation becomes easy ( we may know which room is empty or which room has more people).We used 8051 micro-controller,Temperature and infra-red sensors for this project.
We made another project on home-automation where we were controlling The Light,fan using different modes of communication like Wi-Fi,Bluetooth,Voice,Infrared(Remote).
It was you switch on alight using your mobile Wi-Fi and switch it off by just giving a voice command "Switch Off Light".
