Question
Chapter 13, Problem 5P
Program Plan Intro
Voltage test:
- When the controller operates in RUN mode and the LED status indicator does not illuminate even when the input device is activated, then the voltage test must be performed to predict the error.
- For this purpose, voltage level must be measured across the input terminals.
- If the current voltage level is obtained, then the input module must be changed.
- If the voltage level is not correct, then there might be a possibility of fault in power supply, wiring, or input device.

An engineer was instructed to design a temperature alert and monitoring system for vaccines
storage using NI DAQ and Labview. In order to detect current temperature of the storage, 2
temperature sensors will be used where 1 is located at the front and another sensor located at
the back area. The sensors will read and display current temperature of the storage. A warning
LED will turn ON when of the sensor reach 8°C and danger LED will turn ON when both
sensor reach 8°C. If either one of the sensor reach 2°C. low temperature LED will turn ON.

Prototype room lighting using a touchless switch with your Arduino kit. Use an LED of your choice
for the lighting. Create the circuit such that the LED is turned ON when your hand is above the
photoresistor and turns OFF when your hand moves away from the photoresistor.
Design a password protected door lock system using logic gate. The system must have a mechanism to enter any numeric passwords. The system also should have a display which will show either the entered password is correct or not (using 7segment led display). If the user enter a wrong password he/she will be able to re-enter the password by pressing a specific button of the keypad. For a right
password entry the door will be open.
please explain how the every gate was function to make this system succeed.

The design should take inputs from all of the following four sensors: Sensor A has been set to trigger when the windows in the ward are open. Sensor B has been set to trigger when the relative level of moisture in the air has exceeded 30%. Sensor C is an anemometer and has been set to trigger when the rate of air flow at the ventilation grills has dropped below 20 m/s.

- A data projector projects the text and images from a larger screen to a computer or mobile device screen. True Falsearrow_forwardIn this activity, you will compare closed-loop and open-loop control systems. Background/Scenario An open-loop control system does not monitor the output in order to determine what adjustments to make to the input. For example, when using a clothes dryer you might set the timer on the dryer to run the drying cycle for one hour. At the end of the hour, the dryer will stop. The level of dryness of the clothes will vary depending upon their level of wetness at the beginning of the cycle. In a closed-loop control system, the output is measured to determine whether it is the desired output and adjust the input as appropriate. For example, if the clothes dryer is equipped with moisture sensors, the input may be a level of dryness that adjusts the cycle by extending the drying time until the sensors indicate the clothes are dried to a desired level. Compare the systems listed in the table and determine if they are closed-loop or open-loop control systems.
