Individually or in a group find as many different examples as you can of physical controls and displays.
(a) List them
(b) Try to group them, or classify them.
(c) Discuss whether you believe the control or display is suitable for its purpose. (section 3.9.3 may also help)
The figure below shows a loading truck in a
cement factory. The truck has three wheels,
front wheel (F), middle wheel (M), and back
wheel (B), each wheel has a brake sensor
which is turned ON when the brake is
activated and turned OFF when the brake is
not activated. Also the truck has a weight
sensor (W) which is turned ON when the
truck is full with cement and turned OFF
when the truck is empty. There is a loading
duct which pumps cement into the truck
when the valve controller (V) is ON. Use
multiplexer (MUX) to design a control circuit
that open the valve (V) if the truck is empty
.and anyone of the brakes is activated

Assume you are a software developer that has written a system that analyses pictures of various recyclable items (such as a can, bottle or a crate). It can be used via a Web Application (Web API), i.e., the users send pictures over the Internet. The system returns for each picture how many of each item are seen in the picture. Discuss if this service should be offered for free. Justify your answer

- 2. Draw a state machine diagram that represents the functions of the hardware diagnostic described below: The hadware diagnostic app starts by displaying a hardware diagnostic window. While displaying this window, the user can press a "Search" button to cause the app to start searching for new hardware, or the user can press a "Finish" button to ieave the app. While the app is searching for new hardware, the user may cancel the search at any time. If the user cancels the search, the app displays the hardware update window again. When the app has completed searching for new hardware, it displays the new hardware found.arrow_forwardYou are required to model the requirements of a cruise control system of an automobile. The cruise control system is controlled by a master button. Initially, it is turned on by the master switch. The master switch can be turned off at any time. When it is turned on, the system is in the stand-by mode, the driver of the automobile can press Button + to engage the cruise control at the current speed by accelerating the pedal of the automobile. When the cruise control is engaged, if the driver presses the brake, the system will be disengaged and return to stand-by mode. When the cruise control is engaged, the driver can press Button plus (+) twice to increase speed by one mile per hour or Button minus (-) to decrease speed by one mile per hour. When in the stand-by mode the drive switches off the mater switch it returns to off mode.Construct a state chart or state diagram. Make sure to give the minimum number of states necessary.

- we are interested in an automatic garage gate system for a building. This system includes a gate that goes up or down, a motor to actuate the gate (pull, push) and sensors to collect information (gate open contact, gate closed contact). The sensors are all similar, each signaling to its controller that a contact has taken place. The user has a remote control to control with just two buttons: open, close. The operating principle of the system is as follows. Suppose the gate is closed. The user opens the gate by pressing the Open button on his remote control. He can stop opening by pressing the Open button again, the motor stops. Otherwise, the gate opens completely and triggers a Gate Open sensor which causes the motor to stop. Pressing the Close button causes the gate to close if it is open (partially or fully). The closing can be stopped by pressing the Close button again, the motor stops. Otherwise, the gate closes completely and triggers a Gate Closed sensor which causes the engine…arrow_forwardScreenshot attached.

When sensor detects an object within its range the locker will open otherwise it will be locked and also show message in the display device. You have to build this system using Arduino UNO & if necessary you can use PIR sensor, servo motor and Icd display.
