To conserve energy in an office, you have developed a sensor thatturns on the lights after determining that a person has entered theroom. However, if the person does not push a continue buttonon the device, the lights turn off in two minutes. Design a circuit to hold the lightsfor the indicated time. To help in the solution draw a blockdiagram of the problem, then a circuit diagram, then the requiredcalculations and values for all the circuit elements and finally the results to support the analysis.
