My professor assigned me a project which i have to choose on my on. I t should be a closed loop circuit, means input is applied and a sensor checks the output and if there is any deficiency it increase or decrease the input.
I had an idea of controlling an actual ceiling fan. It should be temperature controlled and must e automatic. when a person enters the room the light as well as fan must starts automatically and when person leaves the room it must turn off automatically.
I don't have any idea how to do this all stuff.
Suggest me another good project or help me out with this project.
