The objective of this lab is:
Continue familiarization with the simulator
Design a Circuit given a specific problem.
Read this page before coming to lab.
There was a shortage of light switches and when we were designing the office and we are limited to only two light switches to light 3 rooms.
The office is required to be energy efficient so no more than one room shall be lit at a time. This means that there are 4 states the lighting of the room can be in:
All lights off
Room # 1 on, all other lights off
Room #2 on, all other lights off
Room #3 on, all other lights off
1.) Design a circuit to complete this task. You will start with an [input | output] table. NOTE: think about how many inputs you need to represent 4 total outputs.
2.) Using Sum of products or Product of Sum, determine the boolean expression for the output
3.) In The simulator, create the Logic Diagram (circuit representation) of the above problem USING only AND, OR, and NOT Gates. You may use LEDs if you wish to represent Lights as LEDs
4.) Create a physical circuit on a breadboard. There should be 3 LEDs on your circuit and you can simply check your circuit by switching all possible combinations of inputs with ground and 5V.
Check your circuit by testing all possible inputs and comparing the outputs to the table you built in part 1. If they match, you have completed the circuit.
Write a lab report with:
your work for creating the boolean equations for part 1 & 2.
a screenshot of your circuit for part 3.
A short summary of what this circuit does.
