You have been selected to design a combinational logic circuit that automatically manages the lights and the cooling/heating system in the classroom. Every classroom has one light (L), one heater (H), and one cooler (C) that you can control (they will be the outputs of your circuit). If L = 1 the light is on; if H = 1 the heating system is on, and if C = 1 the cooling system is on.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
